With a passively mode-locked thin disk Yb:YAG laser we pumped a two-stage optical parametric generator producing ultrashort pulses with 11 W average power at 799 nm and 6 W at 1448 nm. Sum frequency mixing of the latter two wavelengths with residual 1030-nm light results in multi-watt output powers at 450 nm and 602 nm.
