Description
Connet's CoLIS-HP series 1550nm nanosecond long pulse single frequency polarization-maintaining fiber laser is a modularized pulsed fiber laser specially designed for long-distance coherent Doppler wind LiDAR application.
This fiber laser is generally suited for applications which require a long-pulse (in the pulse range of 100ns - 2us). The output of this fiber laser has a single-mode linear polarization with a single-pulse energy up to 150uJ.
CoLIS-HP series 1550nm nanosecond long pulse single-frequency polarization-maintaining fiber laser integrates Connet's proprietary single-frequency narrow linewidth seed laser source with a linewidth as narrow as 5kHz. The extinction ratio can be 100dB or more using a cascaded acousto-optic modulator (AOM), producing a pulsed signal with high turn-off ratio.
This nanosecond single-frequency polarization-maintaining fiber laser adopts an all PM fiber design and can achieve a high polarization extinction ratio (PER). The output fiber end can be integrated with high power three-port optical circulator according to the customer's application requirements.
