Absolute Scale and Spatial Distribution of Nonlinear-Optical Coefficients of GdCOB Crystal
The whole nonlinear optical coefficients of GdCOB crystal are evaluated by phase matching SHG method and Maker fringe method. The spatial distribution of effective nonlinear coefficient d eff are proved with the crystals cut in different directions in the experiments. The results show that d eff reaches the maximum of 1.68 pm/V at the direction of θ=66.8°,φ=132.6°. The SHG conversion efficiency reaches 48% with a 6 mm long GdCOB crystal cut along this direction.
