Generation of quasi-continuous-wave vacuumultraviolet coherent light Yun Zhang ,Yusuke Sato , Nobuyoshi Watanabe ,Riskey Ananda ,Yoshiko Okada-Shudo ,Masayoshi Watanabe We report the generation of quasi-continuous-wave vacuumultraviolet
(VUV) coherent light based on a Ti:sapphire laser with two
successive frequency doubling stages. In the first stage, UV light at 399 nm
with power of 1.1 W was obtained by exploiting an enhanced cavity. With a
KBBF crystal as nonlinear material, quasi-continuous-wave VUV coherent
light with power of about 25 mW at 199.5 nm and 4.7 mW at 193.5 nm
were achieved through a single-pass SHG configuration, respectively, in the doi:10.1364/OE.17.008119 |
