LASER DIODE

Laser diodes operate based on the principles of stimulated and spontaneous emission, as well as absorption. These devices exhibit unique properties such as high directionality, rapid time response, a specific threshold, and exceptional spectral purity, distinguishing them significantly from incandescent light sources.
