CLBO crystals are widely used in laser systems as wavelength conversion crystals in the 190?300 nm range. This is because they have an absorption edge at approx.180 nm, transmitting into the deep UV region, and feature low birefringence.
CLBO crystals have higher laser damage thresholds than other UV wavelength conversion crystals and are attracting increasing attention as the demand for higher-power lasers grows.
Mg:SLN is a LiNbO3 crystal with a stoichiometric composition grown by the DC-CZ method. Compared to regular congruent crystals, it has about 1/1000 the Li defects within the crystal, higher thermal conductivity, and improved photorefractive damage resistance due to MgO doping.It exhibits excellent properties not only for standard wavelength conversion but also for THz generation through high-power laser incidence.
Mg:SLT is a LiTaO3 crystal with stoichiometric composition grown by the DC-CZ method. Compared to conventional congruent crystals, it has about 1/1000 fewer Li defects, higher thermal conductivity, and improved photo-damage resistance due to MgO doping. With a transmission range from the UV region in the 300nm range to the mid-infrared up to 5000nm, high thermal conductivity, and large nonlinear and electro-optic constants, it can be used for wavelength conversion and modulation elements of tens of watts class CW infrared light.
LBGO crystals are ferroelectric materials with an absorption edge at approx. 195 nm that are transparent in the UV region.
It is attracting attention as an UV wavelength conversion crystal that has no hygroscopicity and makes it possible to fabricate Quasi-Phase-Matching (QPM) devices.
Lithium tetraborate (LB4) crystals have potential as materials for polarizers across a wide wavelength range, from the UV to VIS and IR. This is because its absorption edge is at approx. 160 nm, transmitting deep into the UV region, and it features high birefringence. The crystal diameter is approx. 85 mm, making it also suitable for use in relatively large aperturer polarizers.
Our LB4 crystals are grown under optimized conditions to high-quality grade suitable for use as laser optical components.
KTN is a single crystal with a varied Ta/Nb ratio, grown by the TSSG method. By controlling the temperature, a relative dielectric constant exceeding 20,000 can be achieved, exhibiting one of the largest electro-optic effects among existing materials. Furthermore, by injecting electrons into the crystal, it is also possible to develop a function to deflect light.
