Product Description

915nm 55W High Power Pump Laser Diode Gemini Series - K915DG3RN-55.00W
Different from the one 50W, the 915nm 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 915nm 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.
Features:

  •    915 nm wavelength
  •    50W/55Woutput power
  •    105µm fiber core diameter
  •    0.15/0.22N.A. 
  •    1030-1200nm feedback protection 

Applications:

  •    Fiber laser pumping
  •    Medical use
  •    Material processing
