What is a semiconductor laser?
A semiconductor laser—frequently called a laser diode—is a compact, electrically pumped semiconductor device that produces coherent, monochromatic light through stimulated emission, operating on principles similar to light-emitting diodes but utilizing specialized optical cavity mirrors. When an electrical current passes through the semiconductor pn junction, electrons and holes recombine, releasing energy in the form of photons that bounce back and forth between cleaved reflective crystal facets to amplify the light beam. Because of their tiny size, high energy efficiency, and rapid modulation speeds, semiconductor lasers are indispensable components integrated into fiber-optic telecommunications networks, barcode scanners, laser printers, compact disc players, and advanced medical surgical instruments.
