Abstract
We have calculated the theoretical properties of the nonlinear
crystal CsLiB6O10 (CLBO) in third-harmonic generation (THG). Such as
the phase matching angle, effective nonlinear coefficient, walk-off angle,
permitted angle, permitted wavelength, and have found out that the CLBO has
smaller walk-off angle, large permitted parameters as compared with BBO. The
numerical simulation curves of the conversion efficiency are obtained, when
the CLBO is used in THG of the Q-switched Nd:YAG laser with the wavelength
of 1064 nm and of the different pump power, and the optimized efficiency is
as high as 22%, all of which followed that the CLBO crystal is more suitable
to generating a higher order harmonic radiation of intensity power.
