940nm 55W High Power Pump Laser Diode For Laser Pumping- K940FA5RN-55.00W

 
Different from the one 50W, the 940nm 55W High Brightness Diode Laser numerical aperture is 0.22. This one designed also with BWT's proprietary spatial and optical scheme to deliver light into the fiber with high-coupling efficiency. The same 105 um fiber coupling ensures its high brightness. These make 940nm 55 diode lasers provide high power and high brightness for fiber laser manufacturers, material processing and medical application. In addition, inspecting and burn-in procedures in every aspect on every unit guarantee each product will be reliable and high quality.
