Our high power Quasi-CW laser diode, L8411, features several advantages such as high stability with long life, high
cost performance with compact structure, and higher peak intensity. 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.
