22W 975nm Broad Area Laser Diode Drawing:
Broad-area lasers operate in spatial and longitudinal multimodes. They can be used for solid-state laser pumping, sensor technology, material processing, medical applications, photodynamic therapy, and scientific research. Wide-area laser diodes are widely used as pump sources in all-solid-state lasers, while the beam of semiconductor laser diodes needs to be shaped due to the large divergence angle and the asymmetry of the narrow rectangular cross-section in the fast and slow axis directions.
