Semiconductor laser diodes from Mali
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.

How to dissipate heat in laser diodes
Some lasers are passively cooled – the heat from the laser dissipates into the laser case. When operating a laser diode, proper thermal management is critical to avoid damage. How well a solid-state laser is cooled down can also affect its lifetime and reliability, and play a role in its safe operation.

Function of Dutch Laser Diodes
High-power laser diodes are used in industrial applications such as heat treating, cladding, seam welding, and for pumping other lasers, such as diode-pumped solid-state lasers. Dumke in the early 1960s, light emission from a (GaAs) semiconductor diode (a laser diode) was demonstrat.
