How Do They Work?Specifications of A LaserMounting and Positioning Laser DiodesLaser Diodes vs. Helium Neon LasersResourcesLasersproduce highly coherent, directional beams of monochromatic light. The basic structure of any laser is based on an active medium (either a gas or semiconductor) contained between multiple reflectors. A laser''s reflectors contain light by oscillating it through a medium repeatedly allowing the energy to coherently build up with each pass using...See more on edmundoptics IPLTS

OverviewTheoryHistoryTypesReliabilityApplicationsCommon wavelengthsFurther reading

A laser diode is electrically a PIN diode. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively. While initial diode laser research was conducted on simple P–N diodes, all modern lasers use the double-hetero-structure implementation, where the carriers and the photons are confined in order to maximiz
