Abstract
For the first time, the SHG efficiency of RBBF crystal in type-I and type-II phase matching has been simulated. RBBF crystal is pumped by the fundamental radiation of a Q-switched Nd:YAG laser with the wavelength of 1064nm and the shape of plane wave or Gaussian beam. When the pumped radiation is of plane wave, the conversion efficiency of RBBF in type-I and type-II could be as high as 100% and 78%. When the pumped radiation is of Gaussian beam, the conversion efficiency shows a monotonically increasing trend in the type-I phase matching, and in the type-II phase matching the conversion efficiency varies periodically.
