CoWIND Series 1550nm High Power Single Frequency Fiber Laser Module

Connet CoWIND Series 1550nm High Power Single Frequency Fiber Laser Module is an OEM modular narrow linewidth fiber laser designed for short range high precision wind LiDAR applications. Eye-safety working wavelength, single-frequency single longitudinal mode works with a long coherence length. The standard products use polarization-maintaining fiber output, high polarization extinction ratio (PER), output power up to 2W.

Connet CoWIND series 1550nm high-power single-frequency fiber laser module uses the main oscillator power amplifier (MOPA) structure design. The seed laser has single-frequency, low-noise, narrow linewidth characteristics, and the optimized polarization-maintaining fiber amplifiers for power boosting. The modular design is compact and sturdy, suitable for use in a variety of harsh environments, typically used in wind power coherent wind LiDAR, airborne wind LIDAR and so on.

Features:
• Eye-safety wavelength 1550nm
• Narrow linewidth <50kHz
 Long coherent length
 Low RIN, low phase noise
 Single frequency, SLM output
 High polarization extinction ratio (PER)

Applications:

• Coherent Doppler LIDAR
• Environmental monitoring
• Pollution detection
• Coherent communication or sensing
• Other scientific research

Options:
1. High power 3-port optical circulator can be integrated.
2. Non-PM output, higher output power, narrower linewidth down to <5kHz.
