APPLICATIONS OF 1350NM LASERS
Laser diodes producing a wavelength of 1350nm (1.35µm) are versatile enough to be used in an array of applications, including:
- Cosmetic procedures, such as skin tightening
The 1350nm wavelength is in the infrared segment of the electromagnetic spectrum. Light at this wavelength is not visible to the naked human eye. Laser light at 1350 nm is also rapidly absorbed by water.
This rapid water absorption is one of the reasons 1350nm lasers are used for surgery. The laser can quickly ablate targeted tissues, such as tumors, without harming the tissue in the surrounding areas. Lasers also have the added benefit of cutting and coagulating simultaneously.
Researchers have conducted studies using lasers in the 1150 to 1350 nm range for laser tissue welding, to bond wounds without the introduction of a foreign substance. Laser tissue welding allows wounds to heal with very little to no scarring.
Laser diodes at 1350 nm are also useful for purely cosmetic skin treatments, such as skin tightening and wrinkle reduction. Several cosmetic laser treatments operate around this wavelength, sending pulses into the skin and coagulating the tissues in the dermis and hypodermis, without harming the outer layer of skin (epidermis).
