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 manufactured in the laboratory.
The QLD103E-6850 is a 1068-nm distributed feedback (DFB) laser. The laser is mounted into a TO-56 header including a monitor PD for optical power control and hermetic sealed with a flat type cap.
