We report on an eye-safe, transform-limited, millijoule energy, and high average power fiber laser. The high gain and short length of the NP phosphate-glass fibers enable the SBS-free operation with kW level peak power. The output energy is up to 1.3 mJ, and the average power is up to 23 W at an 18 kHz repetition rate with 600 ns pulses (peak power > 2.1 kW). The PER is ≈16 dB and the M2 of the beam is 1.33 × 1.18. The coherent LIDAR Figure Of Merit (FOM) is 174 mJ*sqrt(Hz), which to our knowledge is the highest reported for a fiber laser. We also report 0.75 mJ energy and >3.7 kW peak power with down to 200 ns pulses and up to 1.21 mJ energy with a 3–5 kHz repetition rate operation of the current system.

We report on frequency doubling of 1.55-μm fiber oscillator-amplifier laser with conversion efficiency of 27% by using off-the-shelf nonlinear crystal. The system generates 135-femto-second (fs) pulses with average power of 110 mW at 80 MHz repetition rate. Frequency doubling efficiency as a function of pulse pre-chirp in front of a single mode erbium fiber amplifier was investigated.

Double-pass Pre-chirp managed amplification with high gain and high average power
