CLBO Crystal

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
Sealed crystal mount available

BiBO Crystal

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
Standard and customized coatings available
Strict quality control
Fast delivery

Other opportunities

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. We also have…
