Nonlinear Laser Crystals

A non-linear laser crystal is a type of crystal used in lasers that can generate non-linear optical effects, such as frequency conversion, harmonic generation, and parametric amplification. These crystals have unique properties that allow them to produce multiple wavelengths of light from a single laser source, making them ideal for a variety of applications in science, medicine, and industry.
