Hygroscopic crystal materials deteriorate when they are not constantly saved in sufficiently dry air (or even a dry purge fuel). This is applicable e.g. to KDP and BBO, As well as in a lesser extent to LBO. It might be beneficial to maintain this kind of crystal at a rather elevated temperature, that makes it easier to preserve it dry.
Kingwin Optics features substantial-top quality BIBO crystal with Sophisticated coatings and mounting alternatives, rendering it a superb option for researchers, engineers, and suppliers searching for successful and trusted nonlinear optical elements.
BiB3O6 (BIBO) is an excellent kind of nonlinear Optical Crystal. NLO Crystals BIBO Crystals possesses significant helpful nonlinear coeffcient, huge Sophisticated characteristic for the NLO software broad transparency range between 286nm to 2500nm, high harm threshold and inertness with regard to moisture.
With a large helpful nonlinear coefficient, significant hurt threshold, and inertness to moisture, BIBO crystal presents many positive aspects more than other nonlinear optical materials for instance LBO and BBO.
Also, it can be really appealing to implement a crystal content which can be critically period-matched at room temperature for the reason that noncritical section matching generally requires the Procedure in the crystal inside of a temperature-stabilized crystal oven. Even so, the feasibility of critical stage matching could be given only for adequately large peak powers.
Even if the crystal material or coating is not sensitive to h2o, small h2o droplets may aim laser radiation a lot more tightly than below regular Procedure, and therefore harm the crystal substance.
At this time, as A form of fantastic nonlinear second harmonic crystal, it can be used to produce superior effectiveness crystal of green or blue laser.
Procedure of nonlinear crystals at temperatures below area temperature (to achieve phase matching) is mostly problematic, as it may well bring about condensation of drinking water on the crystal surfaces If your surrounding air just isn't incredibly dry.
In the situation of ultrashort pulses the superior group velocity mismatch enforces using a shorter crystal, which calls for high optical intensities for just a provided conversion effectiveness.
Crystals which might be non-critically period-matched within a crystal oven could exhibit complications if the crystal temperature is modified also rapidly or much too frequently. Specifically, anti-reflection coatings might be harmed as a result of distinctive thermal expansion coefficients with the involved resources.
Bismuth Triborate (BiB3O6 or BIBO) is really a recently made nonlinear optical crystal. It possesses huge helpful nonlinear coefficient, superior damage threshold and inertness with respect to dampness.
GWU-Lasertechnik offers all common nonlinear crystals like LBO, BBO and KTP with a broad selection of technical specs. Beside the effectively-founded supplies, ground breaking crystals like CLBO or BiBO with exceptional Houses for e. g. deep-UV era or significant-energy ultrashort pulse lasers can be more info found. It doesn't matter if individual pieces for R & D reasons are essential or Charge-economical numbers in little, medium or huge batches with in-time shipping and delivery to the manufacturing line are necessary: GWU’s dedicated service really helps to discover the greatest core parts on your application.
The magnitude on the helpful nonlinear coefficient is determined by the nonlinear tensor elements and about the used period-matching configuration. A significant nonlinearity is vital especially In case the achievable optical intensities are lower.
g. in the shape of “grey tracking�? These kinds of phenomena are specially frequent for Procedure with ultraviolet light-weight. Be aware that a gradual degradation might also lead into quick catastrophic destruction by way of extreme warmth era.
