Nonlinear and Laser Crystals

Nonlinear crystals are specialized materials that enable the alteration of laser light frequency through nonlinear optical processes, such as second-harmonic generation and parametric oscillation. These crystals play a crucial role in manipulating light, making them essential components in laser technologies like frequency doubling and optical parametric amplifiers.

Laser crystals serve as the gain medium in lasers, amplifying light when energized by an external source, such as a flashlamp or diode.
