FASCINATION ABOUT A-BBO CRYSTAL

The fundamental subject now driving the Type-I SHG approach would be the Eoγ ingredient on the incident discipline. At γ = 90°, there would be zero SHG output, Because the push discipline Eoγ = 0.The two frequencies' phase velocities are equal if they hold the exact same refractive index. The refractive indices for both of these frequencies are
