NLO & IR Waveplates
Optics for wavelength conversion and polarization control over a wide spectral range. Gooch & Housego has considerable experience in the design and production of crystals for nonlinear frequency conversion applications from the deep UV to the far IR. A wide selection of materials, including, but not limited to AgGaS2, AgGaSe2, BBO, CdS, CdSe, KDP and KD*P are available. Several proprietary software routines enable us to supply "optimized" crystals, which allow you to get the best possible performance from your system. Crystals as large as 41cm x 41cm x 1cm for ICF applications and as small as a few mm in cross section for microchip laser applications are routinely produced. Special geometrical shapes include thin plates, having 200:1 diameter to thickness ratio with diameters as large as 160mm and plates as thin as 400µm for femtosecond-pulse-duration applications. Brewster-cut bars are supplied for low-loss intra-cavity laser applications. Our combined capabilities of crystal growth, device design and assembly, optical fabrication, AR coating, and performance testing result in products with superior performance.
