Abstract
The present invention relates to single crystals of CsB.sub.3 O.sub.5 having large dimension and high quality which can be grown by pulling methods. The single crystals of CsB.sub.3 O.sub.5 are useful as NLO materials. The NLO devices made of CsB.sub.3 O.sub.5 single crystals can be used in a laser system of high power density and relatively large divergence and posses a character of high SHG conversion efficiency. Moreover, the NLO devices of the present invention are capable of producing coherent harmonics of wavelength as short as 170 nm and tolerating larger processing error of crystals.
