These Uncooked materials are very carefully calculated and mixed in exact proportions to make sure the optimal composition from the ensuing crystals.
Optical parametric chirped-pulse amplification (OPCPA): We use OPCPA to ascertain our objects�?nonlinear conversion effectiveness in addition to period-matching angle for a provided input wavelength and sign/idler wavelengths.
Their significant injury threshold and fantastic thermal steadiness make them well suited for use in higher-ability laser programs, while their huge transparency selection enables them to operate by using a broad variety of laser wavelengths.
In the large earth of nonlinear optical crystals, BBO crystals jump out as pioneers, especially in the realm of 266nm generation.
In place of the reference pulse energy spectrum comprising an apodization filter, within the spatial area the filter could well be in NA. The angular domain apodization filter nevertheless, is simply in one-dimension outlined through the airplane k and .
The calculation earlier mentioned assumes a uniform beam depth profile. You need to now look at hotspots from the beam or other non-uniform depth profiles and roughly calculate a most power density.
The second harmonic frequency wave is generated as a unprecedented wave, that's polarized orthogonal to the fundamental-frequency everyday wave.
the chemical durability; e.g., some crystal products are hygroscopic, Other folks bear chemical changes when heated within a vacuum chamber for application of a dielectric coating
Beam diameter is also check here important to know when comparing injury thresholds. When the LIDT, when expressed in units of J/cm², scales independently of spot sizing; huge beam measurements usually tend to illuminate a bigger quantity of defects which may lead to better variances while in the LIDT [four].
If you don't find the acceptable merchandise over, it's possible you'll let's know your prerequisites or purposes in the shape underneath. Our profits or specialized team can get back to you as quickly as possible.
Higher nonlinear coefficients: BBO crystals have significant nonlinear coefficients which make economical frequency conversion procedures with reduced enter energy requires possible.
The production of Beta-Barium Borate (BBO) crystals is a fancy and meticulous procedure that needs a significant standard of precision and knowledge. This process, called the flux technique, commences Along with the preparation of a mix of barium borate and barium fluoride.
3rd harmonic era (THG): We use THG to measure our pieces�?nonlinear conversion effectiveness and section-matching angle for your supplied input wavelength. We Guantee that our solutions fulfill the specs for THG apps.
This is particularly crucial in industries like semiconductors and micro-electromechanical programs (MEMS), exactly where even a insignificant error can render a ingredient ineffective or bring about major losses. With BBO’s 266nm generation, industries can realize greater accuracy and dependability of their fabrication procedures, driving innovation and product excellent to new heights.
