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

For an optical part with some birefringence, you can specify the retardance, that's the difference in stage shifts for The 2 polarization directions.All nonlinear crystals for nonlinear frequency conversion are birefringent. This is due to they might have their nonlinearity only by becoming non-isotropic, and that also leads to birefringence.Intrin
