| Abstract: | We have developed a pulsed Yb:YAG thin disk green laser for pumping a 100 kHz and 10 W femtosecond laser. We optimized numerically
and experimentally the open duration of the acousto-optic (AO) Q-switcher and the internal SHG method, generating stable output
energy at a 100 kHz repetition rate. We demonstrated a 515 nm output power of over 80 W with a pulse-to-pulse stability of
less than 1% RMS with an LD power to green power conversion efficiency of 24%. With the developed green laser, we obtained
16 W of a Ti:sapphire laser in a cavity dumped mode.
