SHG and SFG processes at a 100 kHz picosecond diode-pumped Yb:YAG thin-disk laser

Abstract

Picosecond pulses at 515 nm, 343 nm, 257 nm, and 206 nm were generated in sum frequency processes in nonlinear crystals (LBO, CLBO) pumped by a high-power DPSSL Yb:YAG thin disk laser at 90 kHz repetition rate. Output power and M2 dependencies on the fundamental input power have been measured.
