30 Years of Crystal Experience

GWU-Lasertechnik offers all common laser crystals and standard non-linear crystals with a broad variety of specifications. Beside the well-established materials, there are innovative crystals available with outstanding properties for e. g. deep-UV generation or high-power ultrashort pulse lasers. Crystals and optical components are manufactured by GWU’s partner Castech Inc. The outstanding quality and design flexibility of Castech’s optical crystals and coatings is well-known, supplying thousands of laser manufacturers and researchers worldwide.

Beyond birefringent crystalline materials for frequency conversion, GWU’s range also includes periodically-poled crystals from the pioneer of commercial PPLN, HC Photonics. Besides periodically-poled chips, as bulk or waveguide, for self-integration, our portfolio includes ready-to-use devices (Mixers), either free-space or fiber-coupled.
