Caption

Technician testing a laser diode module. A laser diode is made of two layers of semiconducting material impregnated with impurities that create opposite electrical properties. Passing an electric current through the diode produces a laser beam. The colour of the laser depends upon the semiconducting material used. This laser diode is produced by Photonic Products Ltd.
