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.
