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

Overall, solid-state laser rods play a vital role in various laser systems, offering flexibility in design and performance for a wide range of applications in research, industry, and beyond.
Laser diode
Unlike a regular diode, the goal for a laser diode is to recombine all carriers in the I region, and produce light. Thus, laser diodes are fabricated using direct band-gap semiconductors.
