Increases Power by More Than 50 Percent vs. Comparable Lasers on Market
Peabody, MA – Dec. 16th, 2020 – SemiNex announces its new Gallium Antimonide (GaSb) lasers in the 1900-2400nm range that provide 50% more power than comparable lasers on the market today. The new GaSb laser diodes achieve high power using a GaInAsSb/AlGaAsSb strained QW ridge waveguide technique grown by molecular beam epitaxy (MBE) on GaSb substrates. SemiNex’s 1940nm laser diode demonstrates high optical power of 1.5W and a low threshold current density of less than 100 A/cm2 at room temperature in continuous-wave (CW) conditions. GaSb laser diodes are prevalent in medical, material processing and gas sensing applications.
“The introduction of this new 1940nm laser diode will support our customers in the medical, material processing and gas sensing market with higher power diodes enabling smaller, more efficient, and more effective laser systems,” says Ed McIntyre, VP of Business Development at SemiNex.
Lasers at a 1900-2400nm wavelength play a crucial role in advanced medical procedures such as varicose veins, tonsillectomies and brain surgery.
In a varicose vein procedure, the laser light is absorbed in tissue at a precise target depth to close the vein from the inside quickly without pain. This allows for a shorter operation time with limited scarring.
In a tonsillectomy procedure, laser diodes with a 1940nm wavelength cut through the tissue with reduced pain and increased efficacy when compared to other methods such as electrocautery. 1940nm lasers have twice the absorption coefficient of a 1470nm laser and 100 times that of a 980nm laser; this helps to prevent the mass pooling of blood in procedures such as neurosurgery. In a brain procedure, 1940nm lasers are capable of vaporizing and coagulating tissue, helping to prevent further blood loss and speed up the repair of damaged tissue.
In dentistry, GaSb lasers are used in place of radiographs to detect lesions on teeth which appear as pits and fissures, signs of early occlusal decay. This early find by the laser prevents the need for surgery.
Lasers produced in the 2µm range find use in industrial applications such as the welding of transparent plastics. GaSb laser welders allow the welding of these plastics by focusing 1940nm light that is absorbed strongly by C-H bonds in the polymer. Many transparent plastics share similarities; these plastics can be absorbed adequately by laser light in the 1940-2400nm range permitting direct processing with the lasers. When compared to lasers operating at 1µm, absorption can only be accomplished through additives to the material resulting in a more complex process. Additional applications for material processing in the 1940nm range include the processing and fabrication of bio-fluidic chips, used for biological and medical mass-screening experiments.
“Our GaSb laser didoes in the 1900-2400nm range support businesses in medical, material processing, and gas sensing fields. We are excited to enable our medical systems customers to develop higher power systems that improve recovery times and minimize swelling and scarring with higher performance laser components. We also look forward to improving the performance in plastic welding and gas sensing applications by enabling higher powers and efficiency while reducing the system size and cost,” says David Bean, CEO of SemiNex Corporation.
Lasers with a 1900-2400nm spectral range can detect atmospheric gases such as H2O, CO2 and N2O. Ammonia can be detected through the laser system by exploiting the specific absorption of the gas at a determined wavelength. Backscattered light at this wavelength is compared with the level of returned light at another wavelength to confirm the presence of the gas of interest while eliminating other potential contaminants.
SemiNex GaSb laser diodes at 1940nm are available for immediate delivery as bare chips and in TO9-can packages. Other packages at 1940nm are available upon request with reasonable lead times. Customer wavelengths from 1900-2400nm are available upon request. For more information contact SemiNex or your nearest SemiNex distributor.
Peabody, Mass. – October 28th, 2020 SemiNex has won silver honors in the Laser Focus World Innovators Awards through its new Triple Junction laser diode. The SemiNex 1550nm triple junction laser diode enables a 300 meter eye-safe range for LiDAR systems and provides more than 20 times the photons/second than similar LiDAR at 905nm. The triple junction is the best in its class with 3 times the peak power of other 1550nm diodes. It produces more than 80 watts with 1 watt per amp efficiency enabling automotive LiDAR systems to reach 300 meters, allowing for high speed autonomous travel. Devices are available as a bare chip for integration onto existing control boards, standard TO cans and easy integration into range finding applications.
SemiNex Corporation unveils a new sales and application engineering office in Liaoyang, China to support customers with product selection, system integration, pricing and supply across the entirety of the Asian continent. SemiNex now directly supports new business in Asia for high power laser diodes spanning various industries including consumer devices, professional medical, industrial, military and telecommunications markets. Specifically, the fast-emerging LiDAR applications, including those used in autonomous vehicles, will now benefit from this direct support and the introduction of the new SemiNex Multi-Junction Laser with 300% the power of prior best-in-class lasers. The new multi-junction laser diode produces 80 watts at 1550nm with a 95um aperture width yielding more than 3X the power of current single junction laser diodes at this wavelength.
The Asia office will better support new applications and existing business in China, Korea, Japan, and across Asia. This allows SemiNex to showcase these products directly with the Asian consumer, whereas before, it was only possible to do so remotely, especially with limited travel due to COVID-19 restrictions. An increase in sales, customer satisfaction, and further expansion are already being experienced due to the opening of this new office. SemiNex recently presented its products at the CIOE trade show in Shenzen, China, which in normal years attracts over 89,000 professionals. During the show SemiNex supported dozens of applications and a myriad of customers with in-person meetings.
With the inauguration of this new workspace, SemiNex better responds to customer questions, such as product pricing, specifications, product selection assistance and supply inquires. This comes in a year of pandemic challenges, uncertainty and ever changing variables. Despite these circumstances, SemiNex continues conducting successful business throughout the Far East with increasing sales and support of its laser diodes.
The building, in which the new office is located, is a state of the art structure which recently finished construction. Its central location in Liaoyang allows for easy customer access and convenience, making it effortless to directly schedule in-person meetings, remote calls and web conferences during convenient Asia daily work times.

SemiNex Corporation announces the introduction of a patent-pending, multi-junction, semiconductor laser diode at eye-safe wavelengths between 1310nm and 1550nm with more than 20 times the photons/second and more than 3X the range compared to 905nm LiDAR systems which will enable mass-market auto-driving cars to finally become a reality. The multi-junction laser diode is a drop-in replacement for most compact laser drivers used for existing 9XXnm diode systems. The new SemiNex multi-junction laser diode makes use of 3 monolithic solid-state laser junctions that produce 80 watts at 1550nm with 95µm aperture width and yield more than 3X the power of current laser diodes at this wavelength. Product samples are available immediately and the multi-junction is ready for immediate high volume production.
Typical time-of-flight LiDAR systems using multi-junction 905nm lasers are limited to a range of 100 meters due to eye-safety acceptable emission limits (AEL) of International Electrotechnical Commission (IEC) regulations, thus limiting their use to niche applications such as private security systems, warehouse automation, and limited-use public driving functionality. The new SemiNex multi-junction laser enables high-power, longer-range, lower cost, eye-safe LiDAR solutions for autonomous trains, planes and automobiles.
“SemiNex invested 3 years in research & development to create a long-range and cost-effective solution to overcome the short-range limitations of existing technologies. We see this as a major game changer and believe it will revolutionize the way major LiDAR companies approach this challenge,” said David Bean, CEO of SemiNex Corporation.
The new SemiNex multi-junction laser diode enables eye-safe, autonomous LiDAR systems to reach greater than 250 meters without compromise. Present solutions limit visibility to 100 meters, requiring a vehicles speed to be at 25 mph or less. For the past ten years LiDAR manufacturers have taken two laser approaches for time-of-flight LiDAR systems: 905nm laser diodes or 1550nm fiber lasers. The 905nm laser diodes suffer from limited range due to eye-safety regulations and the 1550nm fiber lasers are impractical for mass market deployment because of their size and cost. Until now, there was no solution that offered the low-cost, small size, and efficiency of 905nm laser diodes with the eye-safety and extended range of 1550nm fiber lasers.
Neither of these past approaches meet the automotive industry goals to enable LIDAR commercialization. The lack of efficient and inexpensive 200 meter eye-safe LiDAR has held back the industry from commercializing autonomous vehicles and seeing any meaningful mass-market deployment at speeds greater than 25 mph. “The SemiNex multi-junction laser diode changes everything,” states Ed McIntyre, SemiNex Director of Sales & Marketing. “Now there is a low-cost, long-range, eye-safe alternative to 9XXnm diodes and 1550nm fiber lasers.”
Today, the LiDAR market for automotive and industrial applications is expected to be $981 million and limited to short range applications. However, with improvements in technology and broader acceptance, the market is expected to grow to $2.8 billion by 2025. A major challenge with the existing LiDAR technology for autonomous vehicles has been to find a cost-effective semi-conductor laser diode that can provide high peak power at eye-safe wavelengths for long range applications. Operating at 1550nm, the SemiNex triple junction device provides 3X the peak power of a single emitter thus improving the resolution and penetration effectiveness in bad weather while remaining eye-safe. It can be operated at pulse widths between 2ns and 100ns at 200kHz to 400kHz pulse repetition rate. SemiNex offers multi-junction devices between 1310nm and 1550nm at various aperture widths and cavity lengths to meet specific customer requirements.
“The SemiNex multi-junction laser diodes will allow vehicles to autonomously navigate at higher speeds that can’t be achieved with the existing technology; this could finally enable driverless cars to be a reality within the next 5 years,” suggests McIntyre.
The multi-junction device is available in double and triple junction configurations in various packaging and submount configurations. Samples in either TO-9 or bare die configuration at 1550nm are available for immediate delivery.

Research by a joint team of scientists from the Max Planck Institute of Quantum Optics and the Ludwig Maximilian University of Munich has led to the first directly diode-pumped Kerr-lens mode-locked Cr2+-doped II-VI oscillator capable of providing average output powers over 500 mW using a SemiNex diode as the diode source. This development will reduce the cost dramatically by more than 5X over the existing common fiber laser technologies available on the market today.
“With this new class of cost-effective and table-top driver for mid-infrared generation, we have taken a crucial step in providing a more accessible alternative to synchrotron-like infrared radiation,” emphasized Nathalie Nagl, Ph.D. student at the LMU Munich.
Cost-efficient MIR sources are requisite to meeting the growing demand in a spectroscopy market estimated to be worth $1.27 Billion by 2022¹. Known as the molecular “fingerprint region,” the mid-infrared can be used to accurately identify samples for pharmaceutical, defense, food safety and manufacturing processes.
The performance of the team’s solution rivals larger, more costly fiber-pumped oscillators by yielding 2.5-times the peak power compared to previous Cr:ZnSe oscillators at 45 fs pulse durations and delivers outstanding low-noise performance.
Other efforts to directly pump Cr:ZnS/ZnSe crystals using diodes in the 1.5-1.6 um regime have been hampered by heat-related issues. SemiNex InP diodes are designed to provide the best thermal performance and highest brightness at these wavelengths in the market today.
“SemiNex is constantly looking to participate with companies and universities to develop innovative technologies that will open new markets for us to participate in. This new approach will impact the availability of lower cost/higher performance portable spectroscopic devices in the mid-IR range,” commented Ed McIntyre, head of Business Development at SemiNex Corporation.
The results of the project were presented at the CLEO conference during this year’s Laser World of Photonics in Munich, and have recently been published in the journal Optics Express². For inquiries about the research team, please contact Nathalie Nagl at Nathalie.Nagl@physik.uni-muenchen.de.
