200 W 1 mJ picosecond laser amplification in a Yb:YAG disk and single-crystal fiber cascade amplifier
A hundred-watt millijoule-level disk and single-crystal fiber cascade amplifier were demonstrated. We innovatively adopted a disk regeneration amplifier as the front end of the single-crystal fiber amplifier. After single-pass amplification by the single-crystal fiber amplifier, a hundred-watt millijoule picosecond laser output is obtained with an average power of 210.1 W and a pulse energy of 1.05 mJ. To the best of our knowledge, this is the first time that the single-crystal fiber amplifier has achieved both hundred-watt and millijoule simultaneously.
