Key Points

  • Improved signal-to-noise ratio leads to enhanced detection range in coherent Doppler wind lidar systems.
  • Integration of a compression gradient fiber amplifier significantly increases peak power through SBS mitigation.
  • The study highlights the benefits of using advanced fiber amplifiers for more precise wind estimation.
  • Implications suggest the need for further exploration of CGFA in various lidar applications.

Abstract

We previously demonstrated the use of a compression gradient fiber amplifier (CGFA) to achieve high peak power through SBS-mitigation. We present in this work the integration of a CGFA into a coherent Doppler wind lidar (CDWL) system to enhance detection range and improve signal-to-noise ratio and wind estimation precision compared to standard fiber amplifier.
