Calculation of Phase Matching Angle of Optical Parametric Amplification
ooe, oeo, eoo, eeo, eoe and oee types phase matching angle calculation formulas in uniaxial crystals are provided. The formulas used for ooe, oeo and eoo types can be applied to both collinear and non-collinear configurations. The formulas used for eeo, eoe, and oee only can be applied to collinear configuration. The numerical methods are provided for non-collinear configuration for eeo, eoe and oee types. The relationship of refractive index between uniaxial crystal and biaxial crystal in principal plane is given. Using this relationship, one can use the method for uniaxial crystal to calculate the phase matching angle in biaxial crystals through replacing the refractive index. The phase matching angles in some common nonlinear crystals are calculated for researchers′ reference.
