Half-kilowatt high energy third harmonic conversion to 50 J @ 10 Hz at 343 nm (2407.11662v2)
Published 16 Jul 2024 in physics.optics
Abstract: We report on frequency tripling of high energy, high repetition rate ns pulses from a cryogenically gas cooled multi-slab Yb:YAG laser system Bivoj/DiPOLE, using a type-I phase matched LBO crystal for second harmonic generation and type-II phase matched LBO crystal for sum frequency generation. We achieved conversion to 343 nm with stable energy of 50 J at repetition rate of 10 Hz and conversion efficiency of 53%.
