Performance of Diode Lasers

Performance of Diode Lasers

Diode lasers are well known as the world's most efficient light source, with records of more than 65% wall-plug efficiency at an emitted power of 12 to 15 W from a 100 µm aperture. 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. In such a heterostructure of a bipolar interband laser, electrons and holes can recombine, releasing the energy. Diode laser technology is well established for biomedicine applications which demand high-power pulse-wave. They are extensively utilized from medical imaging and testing to surgical therapies and the latest aesthetic proce...
