915nm PM Pump Laser Protector

The 915nm PM Pump Laser Protector, also called Pump Protection Filter, 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. Depending on the fiber type of laser diode, we have SM Pump Laser Protector, PM Pump Laser Protector, MM Pump Laser Protector. They can work for 1.0μm fiber laser and 1.5μm fiber laser.

If you do not see a standard Pump Laser Protector that meets your needs, we welcome the opportunity to review your desired specification and quote a custom isolator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.

Above specifications are for device without connector, and the PM PLP device is both axis working.
For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. Power transmits through the connector less than 2W. The default connector key is aligned to slow axis.

Package Dimension

*Due to ongoing design improvements, the package size is subject to change. For high power applications, we will use heat sink package, contact DK Photonics for details. Please contact DK Photonics for confirmation.

Order information

P/N: PMPLP-①-②-③-④-⑤-⑥-⑦

When you inquire, please provide the correct P/N number according to our ordering information and attach the appropriate description would be better. If need any connector, we do not recommend choosing a 250μm bare fiber pigtail. For high power applications, we recommend direct splicing without connectors.
