Generation of 167 W infrared and 124 W green power from a 13-GHz, 1-ps rod fiber amplifier

Year: 2014

Type: article

Abstract: We report on the direct amplification of 1-ps pulses at 1.3 GHz repetition rate by using a large mode area rod fiber amplifier. An average power of 167 W at 1040 nm with nearly transform-limited duration is generated and converted into 124 W average green power through second harmonic generation. Both infrared and green pulses exhibit diffraction-limited beam quality. A frequency doubling efficiency of 75% and a pump-to-green efficiency of 45% have been achieved, which are to our knowledge the highest reported for fiber laser systems.
