摘要：
High efficiency extra-cavity third harmonic generation (THG) of 355 nm has been developed. A laser diode (LD) end-pumped, acoustic-optical Q-switched Nd:YAG laser was used as the fundamental wave source. With an input pump power of 25 W, average power of 6.75 W at 1064 nm was generated with the repetition rate 12 kHz and pulse duration 10 ns. Using the extra-cavity frequency conversion of three critical phase match (CPM) LiB(3)O(5) (LBO) crystals, 3.2 W third harmonic radiation at 355 nm was obtained. The optical-to-optical (1064 nm to 355 nm) conversion efficiency was up to 47.4%. (C) 2010 Elsevier B.V. All rights reserved.
