【Abstract】 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.更多还原
