    High power diode lasers with wavelengths of 1310nm, 1550nm, and 1625nm are ideal for fiber optic communications, whereas high power diode lasers of 1480nm function well as pumps for optical amplifiers. The most common devices are in the range of 808nm through 980nm. Common uses of high power laser diodes include the pumping of the gain medium in solid state lasers, fiber. Laser diodes, which are capable of converting electrical current into light, are available from Thorlabs with center wavelengths in the 375 - 2000 nm range and output powers from 0. We also offer Quantum Cascade Lasers (QCLs) and Interband Cascade Lasers (ICLs) with center. The Tall-TO series with standard TO-9 package offers cw laser diodes up to 600 mW in a space-saving, compact design. This. Laser diodes are electrically pumped semiconductor lasers in which the gain is generated by an electric current flowing through a p–n junction or (more frequently) a p–i–n structure. This GaN laser operates at up to 65 C without significant reductions to the lifetime.
