Gooch & Housego Crystal Optics

G&H produces many different crystals from a variety of materials. They grow, orient, fabricate, finish, coat, and mount beta barium borate (BBO), cadmium sulfide (CdS), cadmium selenide (CdSe), potassium dihydrogen phosphate (KDP), potassium dideuterium phosphate (KD*P) and tellurium dioxide (TeO₂) crystals in housings with apertures from 3 mm to larger than 300 mm.

G&H manufacture their crystals to work in optical components such as acousto-optic modulators, lithium niobate Mach-Zehnder modulators, Pockels cells, waveplates, and harmonic generating crystals. Large KDP and KD*P crystal plates grown, cut, and finished by G&H are used at The Commissariat à l'énergie atomique et aux énergies alternatives (CEA) and National Ignition Facility (NIF) for laser fusion.

G&H has extensive facilities for transmission and reflection interferometry, as well as contrast ratio measurements. We can measure insertion loss, uniformity of birefringence, and other important characteristics.

Our experience growing Lithium Niobate dates back to 1967, producing the first commercially available material. Since that time we have constantly refined the growth and material processing to be able to produce the highest quality, most consistent lithium niobate.
