Paper Abstract

We reported all-solid-state double Nd:YLF and Nd:YAG slab laser and their efficient frequency doubling in near field. With two Nd:YLF slabs fundamental laser pulse energy of 24 mJ and 15mJ pulse energy at 523 nm were obtained at a 1.0 kHz repetition rate. The pulse length at 1047nm and 523 nm was 7.1ns and 5.5 ns. The peak power is around 3MW. The corresponding conversion efficiency was 62.3%. With two Nd:YAG slabs average q-switched fundamental output of 169 W at 10 KHz was obtained. 93 W of second harmonic at 10 KHz with a pulse width of 10.7 ns was achieved. The efficiency of SHG was up to 57%.
