Nd:Ca4ReO(BO3)3(Re=Gd,Y)晶体最佳激光、最佳倍频及最佳自倍频方向的确定

The determination of the optimum directions for laser emission,frequency doubling of Nd:Ca 4 Re O(BO 3) 3( Re =Gd,Y)crystals is discussed. Considering synthetically the anisotropy of the laser stimulated emission cross section ,the absorption coefficient for the pump light, and the effective nonlinear coefficient,we analyze the spatial distribution of the self frequency doubling property,and determine the optimum directions for self frequency doubling.
