Multimode Pump Laser Protector -5W

The Multi-Mode Pump Laser Protector 5w is a passive component which allows maximum transmission from a discrete fibre-coupled pump laser diode and blocks par asitic signals around the centre wavelength of the laser from being reflected back into the laser.

The Multi-Mode Pump Laser Protector 5w is a passive component which allows maximum transmission from a discrete fibre-coupled pump laser diode and blocks par asitic signals around the centre wavelength of the laser from being reflected back into the laser.

Single-emitter laser diodes are highly regarded for their long term reliability. However, these devices are very sensitive to backward propagating light within the delivery fiber. Backward power imaged onto the diode material, as small as 5% of the pump diode output, can cause accelerated diode degradation and, in the majority of cases, catastrophic failure.

DK Photonics offers filter technology that provides protection to pump diodes under these conditions (up to 30 dB). Splicing these filters to the pump output fiber rejects unwanted light before it reaches the diode.

Pump laser protector are available for a wide range of standard light emitting diodes. Fiber pigtails are 105/125 micron, with both 0.15 and 0.22 NA cores available. Operating wavelengths cover the majority of diode laser lines (915 nm, 940 nm, 960 nm and 976) and power handling can be 5W,10W,20W,30W,50W.

If you do not see a Pump Protection Filter from the standard configurations that meets your needs, we welcome the opportunity to review your desired specification and quote a filter best suited to your application. Different pump/rejection wavelengths or fiber pigtail can be accommodated.
