Abstract

A cryogenic Yb amplifier using two laser materials, Gd 3 Sc 2 Al 3 O 12 and Y 3 Al 5 O 12 (YAG), has been used to obtain 70 W average power at 5 kHz pulse repetition frequency; the output was compressed to 1.6 ps , compared with an input compressible to 1.4 ps . The gain broadening obtained by combining two media enables shorter pulses than using Yb:YAG alone but retains the power-scaling advantages of cryogenic Yb:YAG.
