Introduction: | A laser diode is a laser where the active medium is a semiconductor similar to that found in a light-emitting diode. The most common and practical type of laser diode is formed from a p-n junction and powered by injected electric current. These devices are sometimes referred to as injection laser diodes to distinguish them from (optically) pumped laser diodes, which are more easily produced in the laboratory. 658 / 785nm Laser Diode; 90mW@658nm and 15mW@785nm Mitsubishi high power LD(single mode) |
