Nonlinear crystals are crystalline medium used for wavelength (frequency) conversion. The frequency conversion is defined by the crystal orientation as well as transparency spectrum according to the beam propagation (crystal orientation angles). Offered crystals fora wide range of wavelengths are suitable for SHG, THG, FHG, OPO, SM, DFG and other nonlinear effects.
4Lasers is developing different nonlinear crystals for fundamental, applied research and industrial applications. Available crystal growth techniques: Stepanov, Kyropoulos and Czochralski.
We have capabilities to grow these nonlinear crystals:
