HOW MUCH YOU NEED TO EXPECT YOU'LL PAY FOR A GOOD BIREFRINGENT CRYSTAL

This influence can severely Restrict the effectiveness of nonlinear frequency conversion processes, notably when applying tightly centered laser beams.All nonlinear crystals for nonlinear frequency conversion are birefringent. It is because they are able to have their nonlinearity only by getting non-isotropic, Which also triggers birefringence.For
