Overview

Experimental study demonstrates high-energy 1572.3 nm pulses in an erbium-doped fiber amplifier, highlighting advanced capabilities for atmospheric carbon dioxide LIDAR detection.

Key Points

  • Develop a polarization-maintaining, very-large-mode-area erbium-doped fiber amplifier capable of delivering high-energy optical pulses at 1572.3 nm for atmospheric carbon dioxide sensing.
  • Fabricated a polarization-maintaining, very-large-mode-area erbium-doped fiber amplifier with an effective mode area of approximately 1100 μm².
  • Core-pumped the amplifier using a Raman fiber laser to amplify single-frequency, 1-microsecond optical pulses.
  • Generated 1572.3 nm pulses with a pulse energy of 541 μJ and a peak power of 700 W.
  • Maintained high beam quality with an M² of 1.1 and achieved a polarization extinction ratio greater than 20 dB.
