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 others. 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 phase-matching, a high nonlinear coefficient, high optical damage threshold, and other properties.
