Where to Buy Optical Materials

Whether your application works in the visible, ultraviolet (UV), near-infrared (NIR) or infrared (IR) spectrum, we have a wide variety of wavelength-specific substrates for customisation or from our extensive stock range. From BK7 (or equivalent), UV-grade fused silica and quartz to germanium, sapphire and zinc selenide – plus many more substrate alternatives – our components are capable of meeting any requirement.

ICC offers optical crystals of CaF₂, MgF₂, LiF₂, BaF₂, silicon, germanium and ZnSe. ICC is China's largest manufacturer of fluoride crystals.

Periodically poled lithium niobate: magnesium-doped PPLN is ideal for innovative laser applications due to its high effective nonlinear coefficient; allowing for high efficiency frequency conversion across multiple different mechanisms.

Covesion is a world leader in the design and manufacture of periodically poled lithium niobate for non-linear frequency conversion. MgO:PPLN crystals are available for high efficiency SHG, DFG, SFG and OPO interactions. Wavelength generation coverage runs from visible to mid-IR.

Periodic poling allows for quasi phase matching, which maintains phase relation of the photons throughout the crystal where they would otherwise fall out of phase. This engineered effect leads to a much higher conversion efficiency than would be found in the regular crystal.

Readily available stock crystals and waveguides can be provided on short timescales to rapidly meet your application needs, providing the capability to generate laser light in a wide range of wavelengths.
