A: Yes, BBO crystals exhibit spectacular thermal stability, building them suited to apps with varying temperatures.
Hi, thanks for getting in touch with Thorlabs. The wavelength ranges on the antireflective coatings on these β-BBO crystals align Along with the respective wavelength bands that these crystals are optimized for. Requests for customizations is often made by reaching out to us at [email protected]
However, it can be quite challenging to compare the LIDT specification of an optic to your laser. There are numerous regimes in which a pulsed laser can harm an optic which is based on the laser's pulse duration. The highlighted columns in the desk below outline the applicable pulse lengths for our specified LIDT values.
As the next harmonic light propagates, its Electrical power flows in a distinct course than that of the elemental light.
Next harmonic technology (SHG): We utilize SHG to evaluate our things�?nonlinear conversion efficiency and phase-matching angle for a offered input wavelength. We promise that our objects fulfil the requirements for SHG applications.
They exhibit very good homogeneity about big volumes and have a high hurt threshold, but are hygroscopic and possess a reduced nonlinearity.
This publish-up will describe how we produce higher-quality BBO crystals at our corporation. We may also review some strengths and problems of using BBO crystals for regularity conversion.
Together with their use in laser frequency conversion, BBO crystals have found apps in electro-optic modulation and quantum optics experiments.
) to blow off dust and various free contaminants to start with. If a dry nitrogen line is on the BBO Crystal market in the lab, an air gun can also be made use of to blow away dust particles. Blow from the surface gently. Never blow from the crystal alone from the hand!
For CPM, we Reduce our parts at an angle equal to no or ninety levels worrying on the list of key axes. For NCPM, we minimized our products at an angle based on Snell’s regulation:
The raw elements, normally a mixture of barium carbonate and boric acid, are put within a platinum crucible and heated till they soften. The temperature is then steadily lessened, making it possible for the BBO crystal to form about numerous months. The crystal is then extracted, Lower into the specified form, and polished to realize a substantial-top quality optical area.
BBO nonlinear crystal is often a damaging uniaxial crystal. It offers period matching for numerous next-purchase interactions Pretty much in excess of its entire transparency assortment. This transparency ranges from 185 nm to 3.3 µm, as inferred from transmittance measurements working with crystal samples of some mm thickness.
With appropriate care and dealing with, BBO crystals can previous for a few years. Even so, their lifespan might be shortened by components for instance substantial temperature, humidity, and Actual physical injury. BBO crystals are strong and sturdy, but like any optical component, they will degrade over time if not correctly cared for.
Inspect the crystal surface for dust and stains by holding it around a shiny obvious-light source. Viewing at distinct angles will help see scattering from dust and stains. The crystal area has to be cleaned as described under if dust and stains are observed.
