Abstract

With the amplification of 380 fs, 1 mJ ultrashort pulses with a nearly diffraction limited beam quality, Yb:YAG single crystal fibers (SCF) have recently proven their strong potential as power amplifier. Furthermore, during a first power scaling experiment, up to 250 W continuous wave (cw) power were obtained from an Yb:YAG SCF oscillator at 570 W of pump power. In this paper, we present a power scaling experiment of Yb:YAG SCF amplifiers.
