1550nm High Power Single Frequency Fiber Laser (CoWIND Series-Ideal Source for Short-distance Wind LIDAR)

1550nm高功率单频光纤激光器模块
Connet CoWIND series 1550nm High Power Single Frequency Fiber Laser module is a modularized narrow linewidth fiber laser specifically designed for short-distance high-precision Coherent LIDAR for wind sensing. Based on eye-safety operating wavelength, the laser is with single frequency single longitudinal mode operation with a long coherence length. The standard laser uses the polarization-maintaining fiber output to realize the high polarization extinction ratio (PER)and the high output power up to 2W.

This CoWIND series 1550nm high power single frequency fiber laser module adopts the Master Oscillator Power Amplifier (MOPA) structure design. The seed laser is with the characteristics of single frequency, low noise and narrow linewidth. The optimized polarization-maintaining fiber amplifier is for power boosting. The compact and robust modular design is suitable for various harsh environments, typically applied to Coherent Wind LiDAR in wind power field and airborne wind LIDAR, etc.
