摘　　要：We present results of frequency tripling experiments performed at the Hilase facility on a cryogenically gas cooled multislab ytterbium-doped yttrium aluminum garnet laser system, Bivoj/Di POLE. The laser produces high-energy ns pulses at 10 Hz repetition rate, which are frequency doubled using a type-I phase-matched lithium triborate(LBO) crystal and consequently frequency summed using a type-II phase-matched LBO crystal. We demonstrated a stable frequency conversion to 343 nm at 50 J energy and 10 Hz repetition rate with conversion efficiency of 53%.
