Beta-Barium Borate (β-BaB2O4 or BBO) is a widely used crystal providing high non-linear optical properties from the UV across the visible to the IR spectral range. Castech holds the specialized proprietary techniques (flux-method) for BBO crystal growth, ensuring the steady availability of high-quality crystals.
Spezifications:
Broad phase-matching range from 409.6 nm to 3500 nm
Wide transmission range from 190 nm to 3500 nm
High non-linear optical coefficients for highly efficient frequency conversion
Low temperature sensitivity – wide temperature acceptance bandwidth
Cesium Lithium Borate (CsLiB6O10, CLBO) is a newly developed crystal with excellent nonlinear UV features. Compared to BBO, it has a higher spectral and temperature acceptance, larger angle tolerance and smaller walk-off angle. The transparency ranges down to 180 nm. These advantages make CLBO a perfect material for UV and deep UV applications.
Spezifications:
Wide deep-UV transmission down to 180 nm
Large effective NLO coefficients
Wide acceptance angle
Small walk-off
No saturation effects for high-power UV generation
Bismuth Triborate (BiB3O6, BiBO) is a newly developed crystal with high non-linearity perfectly suitable for e. g. the generation of visible light. No matter if individual pieces for R&D purposes are required or cost-efficient numbers in small, medium or large batches with in-time delivery for the production line are needed: GWU’s dedicated service helps to find the best core components for your application.
Spezifications:
High non-linear coefficient
High damage threshold, insensitive against moisture
Crystal dimensions available up to 10 mm x 10 mm x 15
Lithium Triborate (LiB3O5 or LBO) is an excellent non-linear material for a broad variety of applications. Castech holds the exclusive rights to produce the patented LBO crystal and its NLO devices (patent number is 4,826,283 in USA, 2023845 in Japan and 88 1 02084.2 in China). No matter if individual pieces for R&D purposes are required or cost-efficient numbers in small, medium or large batches with in-time delivery for the production line are needed.
Spezifications:
High non-linear optical coefficients for highly efficient frequency conversion
High damage threshold
Wide acceptance angle and small walk-off
Non-critical phase-matching possible for a wide wavelength range
