This efficiency is important, especially when one considers the era in the 266nm wavelength, wherever even insignificant inefficiencies may result in sizeable Electrical power losses.
Hello there, thank you for getting in contact with Thorlabs. The wavelength ranges with 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 usually created by achieving out to us at techsupport@thorlabs.com

Additionally, spectroscopy, a method that’s fundamental in analyzing and knowledge the Houses of assorted substances, reaps the benefits of BBO’s abilities. Spectroscopy relies on the interaction in between light and subject to derive insights a couple of material’s composition, framework, as well as other Homes.
BBO crystals might be cleaned using a delicate cloth or air blower. For stubborn stains, a delicate detergent or isopropyl Liquor can be employed. It’s essential to keep away from making use of abrasive resources that would scratch the crystal’s surface. When cleansing BBO crystals, it’s important to use a mild, circular motion in order to avoid scratching the floor.
If the crystal surfaces remain “soiled�?soon after the above mentioned cleansing strategies, the surfaces might have been damaged. Make sure you Speak to us for rework of your crystals.
Filters down below or the form at The underside can be used to aid products research or make more inquiries.
In addition to their use in laser frequency conversion, BBO crystals have discovered purposes in electro-optic modulation and quantum optics experiments.
BBO crystals are delicate website and require cautious managing to forestall harm to their surfaces. They must be taken care of with cleanse, lint-absolutely free gloves to stay away from scratching or contaminating their surfaces. When not in use, BBO crystals should be saved inside a awesome, dry put away from immediate sunlight, as prolonged exposure to warmth and light-weight can degrade their optical Houses.
It is typically important to concentrate the incident light during the crystal for SHG apps, since effective technology of next harmonic mild necessitates high peak intensities, which include 109 W/cm2. When working with femtosecond pulses with reasonable energies inside the nanojoule variety, obtaining the expected peak intensities can need little focal spots.
We use Numerical Aperture (NA) to explain the extent of the angular information. Preferably, the fundamental laser gentle can be collimated all through the crystal, given that collimated mild resembles a gaggle of rays aligned to the same direction having an NA of zero.
Many alternative Houses of a nonlinear crystal can be critical for an application e.g. in nonlinear frequency conversion:
The 266nm generation refers to the production of ultraviolet gentle with a wavelength of 266 nanometers.
Humidity could potentially cause h2o absorption over the crystal floor, which could degrade its optical efficiency. The quality of the incident gentle, which includes its wavelength, depth, and polarization, could also have an effect on the performance of BBO crystals in several apps.
