CoWIND 1550nm High Power Single Frequency Fiber Laser Module
Product Description:
CoWIND Series 1550nm High Power Single Frequency Fiber Laser Module of Connet is an OEM modular narrow linewidth fiber laser designed for short range high precision wind LiDAR application. The eye-safe working wavelength is adopted. The single-frequency single longitudinal mode ensures the long coherence length. The standard model of this laser uses the polarization-maintaining fiber output, high polarization extinction ratio (PER) with the 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 is with the single-frequency, low-noise, narrow linewidth characteristics and meanwhile the optimized polarization-maintaining fiber amplifier is adopted for power boosting. The modular design is compact and robust, which is applicable to a variety of harsh environments. This laser can be widely used in wind power, coherent wind LiDAR and airborne wind LIDAR, etc.
Options:
1. High power 3-port optical circulator can be integrated.
2. Non-PM output, higher output power, narrower linewidth down to <5kHz.
Applications:
● Coherent Doppler LIDAR
● Environmental monitoring
● Pollution detection
● Coherent communication or sensing
● Other scientific research
Features:
● Eye-safe wavelength 1550nm
● Narrow linewidth 10kHz
● Long coherence length
● Low RIN, low phase noise
● Single frequency, SLM output
● High Polarization Extinction Ratio (PER)
