Princeton Optronics Inc.Request Info
 
Princeton Optronics Inc. has introduced an 808-nm semiconductor laser that is suitable for use in medical devices. The system (PO-CS1-70-W808) consists of a 2-D planar vertical-cavity surface-emitting laser (VCSEL) array mounted on a high thermal conductivity submount. It produces 70 W of output power in CW mode, with a spectral width of about 0.8 nm, a thermally stable emission wavelength (0.06 nm/K) and low beam divergence. It is immune to backreflections and can operate at high temperatures of up to 80 °C. It can be operated in quasi-CW or short-pulsed (<20-ns) modes.

GLOSSARY
semiconductor laser
A semiconductor material which is designed and grown for the efficient production of short wavelength stimulated emission through high gain as well as low internal losses. Materials with band gap energies which emit radiation efficiently within the desired wavelength region are used. Diodes may emit vertically in relation to the laser material junction in a VCSEL configuration or horizontally in an edge emitting configuration. Synonymous with laser diode.  Sometimes used...
