It can be applied as light source to pump solid state lasers, for material processing like welding or soldering, and for medical systems. The lasing areas consist of small laser emitters arranged in line and are thus called “Bar” structure. A high Quasi-CW output power as high as 10kW at peak was achieved by stacking ten Bars. Cooling methods can be selected from Peltier-cooling, water-cooling and Funryu-cooling (patent pending : Japan 8-139479, WO 00/11717). A high power laser module with a focusing lens and a driving electronics are optionally available.
