We present sum-frequency generation (SFG) characteristics of CSB3O5 cr
ystal (CBO), The effective nonlinear-optical coefficient of CBO in the
ultraviolet range is close to its maximum. High-efficiency SFG with a
picosecond Nd:YAG laser with output wavelengths of 355 and 266 nm was
achieved. Experiments showed that CBO can be used under high power de
nsity without damage to the crystal. (C) 1997 Optical Society of Ameri
