1550nm Long Pulsed Single Frequency Fiber Laser For Coherent Doppler LiDAR
1550nm Long Pulsed Single Frequency Fiber Laser for Coherent Doppler Lidar (CDL) systems which are suitable for wind sensing of localized regions under clear weather conditions.The long pulsed single frequency polarization-maintaining fiber laser is a modularized pulsed fiber laser designed for long-distance coherent Doppler wind LiDAR application. Based on eye-safe operating wavelength, the fiber laser is suited for long-pulse applications, can produce a single-mode linearly polarized output.
Integrated with our particularly designed single frequency narrow linewidth seed laser source, the narrow linewidth can be down to 5kHz. Utilizing the cascaded acousto-optic modulator (AOM) to produce pulse signal with high turn-off ratio, the extinction ratio can exceed 100dB.
This single frequency fiber laser adopts design of all polarization-maintaining (PM) fiber, achieving high polarization extinction ratio (PER) output. According to the requirements of application, high power three-port optical circulator can be integrated at the output end.
Eye-safe operating wavelength: 1550nm
Single pulse energy: up to 150uJ
Repetition rate adjusting range: 5-20kHz
