Photonics uses light and similar radiant energy in equipment such as lasers, optics and imaging devices for a wide range of applications from communications and information processing to lighting, agriculture and medicine, manufacturing, transportation, and aerospace. Lasers are used for welding, drilling, etching and cutting of metals, fabrics and even human tissue. Coherent light beams and fiber optics transmit data using light, while spectral analysis can identify gases and solids using photonic technology.
Photonic technologies that use lasers require precise and reliable power supplies as laser diodes are current-sensitive. Fault protections built into the power supply are critical to safeguarding the laser equipment.
