Amplification Characteristic of Low Temperature Yb:YAG Crystal Disc Cooled by Alcohol
We describe a low temperature Yb:YAG crystal disc laser amplifier cooled by alcohol and stuided detailed the re-absorption of Yb:YAG crystal at different temperatures. The amplifier′s characteristic has a decided change with different temperatures. For double-pass amplifier, the small signal gain of 3 is obtained at the temperature of 213 K when the pump energy is 2.17 J. For four-pass amplifier, the output energy of 60 mJ per pulse is obtained, corresponding to a small signal gain of 9.
