As diode lasers are semiconductor devices, they may also be classified as semiconductor lasers. 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 respectivel.

For diodes still on the wafer, such as Vertical Cavity Surface-Emitting Lasers (VCSELs), or in a bar (edge emitting lasers), pulsed testing is essential because the devices have no temperature control circuitry at that point. The effect of temperature o the performance of uncooled semiconductor LD was experimentally studied. Why do Wavelengths Shift in Laser Diodes? Laser diodes differ fundamentally from gas lasers in how their emission. Semiconductor lasers generate a small amount of heat during operation, so their performance varies at different temperatures. In a conventional 1300 nm, fiber-pigtailed diode laser package the internal thermoelectric cooler can change the laser chip temperature from room temperature to 0℃ in 2 or 3 seconds with the application of less than a watt of electrical power.
