Abstract

Abstract We report on frequency doubling of high-energy, high repetition rate ns pulses from a cryogenically gas cooled multi-slab ytterbium-doped yttrium aluminum garnet laser system, Bivoj/DiPOLE, using a type-I phase matched lithium triborate crystal. We achieved conversion to 515 nm with energy of 95 J at repetition rate of 10 Hz and conversion efficiency of 79%. High conversion efficiency was achieved due to successful depolarization compensation of the fundamental input beam.

千瓦级高能频率转换为95j, 10hz, 515nm

本文报道了利用i型相匹配的三硼酸锂晶体，从低温气冷多板掺镱钇铝石榴石激光系统Bivoj/DiPOLE中获得的高能、高重复率ns脉冲的倍频。我们以95 J的能量在10 Hz的重复频率下实现了515 nm的转换，转换效率为79%。通过对基波输入光束的去极化补偿，实现了高转换效率。
