Nonlinear optical crystals are used in many different nonlinear parametric applications. To mention a few, second harmonic generation, difference frequency generation, optical parametric amplification and other. A proper crystal has to be chosen in order to use it for a particular application. It should have: transparency in the required spectral range, adequate birefringence for phasematching, a high nonlinear coefficient, high optical damage threshold.
