The superior damage threshold of BBO crystals is especially important in environments where by substantial-depth lasers are definitely the norm. Common components may well falter, degrade, or maybe split beneath this kind of intensities.
The 266nm wavelength offers precise interactions that other wavelengths can’t, rendering it indispensable for detecting and researching particular compounds.
Howdy, thanks for contacting Thorlabs. The wavelength ranges of the antireflective coatings on these β-BBO crystals align Together with the respective wavelength bands that these crystals are optimized for. Requests for customizations is usually made by achieving out to us at techsupport@thorlabs.com
This improvement in clarity can lead to early diagnosis and timely intervention, probably preserving life and enhancing individual results.
We use Numerical Aperture (NA) to explain the extent of this angular content. Ideally, the elemental laser light-weight could be collimated through the crystal, considering that collimated light-weight resembles a group of rays aligned to the same way with the NA of zero.
As the 2nd harmonic light-weight propagates, its Power flows in a special course than that of the elemental light-weight.
The realm of fabric processing has Similarly benefited with the precision of 266nm era. Sophisticated microfabrication processes, which entail intricate detailing on elements at a microscopic level, need a precise mild source. The sharpness related to the 266nm wavelength ensures that lasers can make precise cuts, etches, and modifications.
Some suppliers' SHG crystals, which include Thorlabs', supply near-period-matched ailments for Generally incident input gentle to get a specified fundamental frequency. These manufacturers polish the faces of the SHG crystals these the angle amongst the Commonly incident mild as well as the optic axis is the phase-matched angle for the specified frequency.
In summation, though many crystals offer precise strengths inside the realm of photonics, BBO crystals arise as detailed powerhouses. They encapsulate A selection of features that are not just useful in isolation but get here the job done synergistically, making a holistic Resolution for frequency doubling and harmonics era.
A5: Indeed, BBO crystals have fantastic thermal balance and might keep their Houses at area temperature. This means that they can be Utilized in a variety of environments with no requiring Unique temperature Command.
The Uncooked elements, usually a mix of barium carbonate and boric acid, are positioned in the platinum crucible and heated right up until they soften. The temperature is then slowly minimized, allowing for the BBO crystal to kind in excess of several months. The crystal is then extracted, Slice into the specified condition, and polished to achieve a high-top quality optical surface area.
In the huge environment of nonlinear optical crystals, BBO crystals stand out as pioneers, particularly in the realm of 266nm generation.
The 266nm generation refers back to the creation of ultraviolet mild with a wavelength of 266 nanometers.
Era of deep ultraviolet radiation at 210 nm by Style-I 3rd harmonic technology is reached within a pair of BBO crystals with conversion efficiency as large as 36%.
