Alfa Chemistry provides customers with a variety of optical crystals in addition to the well-known nonlinear and laser crystals.
Birefringence is an optical property of a material whose refractive index depends on the polarization and direction of propagation of light. Birefringence is often quantified as the maximum difference between the refractive indices exhibited by a material. Numerous birefringent crystals are available from us, including YVO4, calcite, and a-BBO crystals.
Barium fluoride (BaF2) crystals with holographic crystal orientation are used to generate cross-polarized waves. We offer [011]-oriented BaF2 optical crystals for cross-polarization wave generation.
The phenomenon that the transmittance of an optical material at a specific laser wavelength depends on the laser intensity is used by passive Q-switching devices to accomplish Q-switching. For research and industrial applications, we create and distribute various mixes of passive Q-switched crystal hosts and ion dopants, enabling the provision of customized solutions upon request.
The photorefractive effect is a phenomenon in which the local refractive index is modified by spatial variations in the intensity of light. We offer photorefractive crystals for applications that exploit the photorefractive effect.
We offer high quality scintillation crystals that absorb high energy radiation and convert the energy into short bursts of visible photons for research, medical and industrial applications. These crystals have great features such as high density, fast operation, high radiation hardness, and high quality to price ratio.
Inelastic photon-phonon interactions in Raman crystals cause a Stokes or anti-Stokes shift of the pump radiation. We offer multiple Raman crystals.
