H. Kiriyama et al., Quadrature frequency conversion scheme using CsLiB6O10 crystals for the efficient second-harmonic generation of high power Nd : YAG laser, OPT REV, 7(4), 2000, pp. 281-283
The ability of CsLiB6O10 (CLBO) crystals for high power second-harmonic gen
eration (SHG) of a 1064-nm Nd:YAG laser in a quadrature arrangement was exp
erimentally demonstrated. A 532-nm second harmonic output pulse energy of 2
.25 J was obtained with 3.21 J of an input 1064-nm fundamental pulse energy
at a repetition rate of 10 Hz, corresponding to a power conversion efficie
ncy in excess of 70%.
