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.

Earlier, in 1962 Boyle and colleague, Don Nelson, developed the ruby laser in 1962, and with another colleague, David Thomas, he helped to develop the semiconductor injection laser, which is found in many electronic appliances.
Scientists from Harvard Univ., Cambridge, Mass., Texas A&M Univ., College Station, and Bell Labs, Somerset, N.J., have laid the foundations for a new type of "plug-and-play" laser--the Raman injection laser. Raman lasers have been used for a long time, but "in general they require a large and powerful external pump to compensate for the beam's attenuation as it propagates through the material," says Mariano Troccoli, Harvard research member.
