The Application Of Optical Crystals

Optical crystals are crystal materials used as optical media materials. Optical crystals are divided into single crystals and polycrystals according to their crystal structure. Single crystal materials have high crystal integrity and light transmittance, as well as low input loss, so the commonly used optical crystals are mainly single crystals. Optical crystals are widely used in optical devices such as lasers, modulators, optical amplifiers, and optical isolators, as well as in fields such as spectroscopic analysis, biological imaging, and medical diagnosis.

The working principle of optical crystals

Firstly, nonlinear optical crystals are functional materials in which frequency doubling or conversion crystals can be used to convert laser wavelengths, thereby expanding the tunable range.

Secondly, linear optical effects are the foundation of classical optics and are widely used in the design and manufacture of optical components such as lenses, mirrors, waveplates, and diffraction gratings.

Thirdly, photonic crystals are crystal structures composed of dielectric materials with different refractive indices arranged periodically in space.

Fourthly, the spectroscopic crystal is the core component of the crystal spectroscopic system, equivalent to the prism and grating in optical spectrometers.
