Abstract
The theory of optical parametric generator in BBO crystal is analysed and optical parametric generator is Pumped by the second, third and fourth harmonic of YAG mode-locking laser. The following experimental results are obtained such as the influence of the physical parameters on the threshould, the conversion efficiency ( over 30% ) and the bandwidth of optical parametric generator in BBO crystal.
