Injection Laser

injection laser

[in′jek·shən ¦lā·zər]
(optics)
A laser in which a forward-biased gallium arsenide diode converts direct-current input power directly into coherent light, without optical pumping.

Injection Laser

 

a semiconductor laser in which injection of electrons and holes into the region of the p-n junction is used. An injection laser is distinguished in its small size (volume, approximately 1 cu mm). Injection lasers are based on a large number of semiconductor materials; they radiate in a broad range of wavelengths, from visible light to infrared radiation.
