SemiNex Product Offerings at 1,550nm
SemiNex provides diode lasers with wavelengths of 1550nm in a variety of systems. 1550 nm diodes can be mounted on a B-Mount, C-Mount, as a Chip on Submount, or as individual Chips and Bars. Diodes can also be purchased in our High Heat Load or 4-Pin packages, or in our Multi-Chip Module. Our patented Laser Engine can also be equipped with a 1550nm laser.
Applications for 1550nm

1550 nm in Rangefinding
Rangefinder systems that are built with 1550 nm laser diodes operate at high power eye-safe wavelengths. 1550 nm lasers are eye-safe at much higher power levels since this wavelength is not focused by the eye, but the detector technology is less advanced and so these wavelengths are generally used at longer ranges and lower accuracies. They are commonly used for military applications because 1550 nm is not visible in night vision goggles unlike the shorter 1000 nm infrared laser.|

LIDAR Applications Using 1550nm
1550nm diodes are commonly used as high power, eye safe alternatives to lasers in 600nm-1000nm light range in LIDAR applications because 1550 nm laser light is not focused by the eye. 1,550nm laser technology is typically used for long range, lower accuracy LIDAR measurements. 1,550 nm light is also not visible to night vision goggles, and is thus popular for military LIDAR applications.
1,550nm and Cosmetic Nonablative Procedures
The use of the 1550nm wavelength has proven effective for treating acne scarring and atrophic scarring, for skin resurfacing and skin rejuvenation, and for reducing wrinkles and pore size. The rejuvenating and healing effects of the 1550nm wavelength are significant. As the laser is applied to the skin, the heat from the laser damages the epidermis. The damage encourages collagen remodeling and rapid healing of the epidermis, resulting in reduced scarring and increased skin durability and tightness. This is a nonablative treatment and thus requires significantly less downtime than ablative treatments, with options for more frequent and thus more significant long-term changes than ablative treatments. The 1550nm wavelength has been effectively tested in treating Asian patients with skin Fitzpatrick skin types IV and V.
