- Polarization Maintaining Laser Pump Protector for femtosecond or Picosecond fiber laser

Description

Polarization Maintaining Pump Protector

CSRAYZER’s Polarization Maintaining Pump Laser Protector PMPP Series products, also called Pump Protection Filter, is a passive component which allows maximum transmission from a discrete fiber-coupled pump laser diode and blocks parasitic signals around the centre wavelength of the laser from being reflected back into the laser. Depending on the fiber type of laser diode, we have SM Pump Laser Protector, PM Pump Laser Protector, MM Pump Laser Protector, used for 1.0μm fiber laser and 1.5μm fiber laser, with high isolation, low insertion loss.
