This efficiency is important, particularly when one considers the generation in the 266nm wavelength, exactly where even small inefficiencies can cause important Electricity losses.
Good day, thank you for getting in contact with Thorlabs. The wavelength ranges in the antireflective coatings on these β-BBO crystals align with the respective wavelength bands that these crystals are optimized for. Requests for customizations might be created by achieving out to us at [email protected]
Both of those have a comparatively low harm threshold, but don't need to be operated at large intensities due to their large nonlinearity. They may have a tendency for photorefractive results, that are harmful for frequency conversion, but are employed for, e.g., holographic information storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive harm�?relies upon strongly on the material composition; e.g. it may be lessened through MgO doping and by using a stoichiometric composition.
The Z-axis is parallel towards the optical axis on the crystal as well as is Also called the fantastic axis. The X- and Y-axes are parallel into the optical axis and they are identified as typical axes.
For beams which has a high PRF both of those the normal and peak powers should be compared to the equivalent CW energy. Also, for very transparent resources, You can find very little to no fall in the LIDT with raising PRF.
A common process for getting ultrathin crystals will be to very first optically Get in touch with a thicker nonlinear crystal with a few substrate (e.g. of fused silica) after which to shine the crystal right down to the needed thickness of e.

BBO crystals are a significant component in many optical purposes due to their Fantastic Houses. Comprehension their creation, Homes, dealing with, and use might help consumers enhance their effectiveness and lifespan.
BBO crystals are sensitive and demand very careful managing to forestall damage to their surfaces. They must be managed with clear, lint-cost-free gloves in order to avoid scratching or contaminating their surfaces. When not in use, BBO crystals must be stored inside of a amazing, dry spot clear of immediate sunlight, as extended exposure to warmth and light-weight can degrade their optical properties.
GWU-Lasertechnik features all common nonlinear crystals like LBO, BBO and KTP having a broad variety of specifications. Beside the perfectly-recognized resources, revolutionary crystals like CLBO or BiBO with superb Attributes for e. g. deep-UV era or high-electricity ultrashort pulse lasers are offered. Despite if person items for R & D functions are required or Value-effective quantities in tiny, medium or large batches with in-time shipping and delivery for that production line are essential: GWU’s devoted service really helps to locate the ideal Main components to your application.
The raw products, usually a mix of barium carbonate and boric acid, are positioned within a platinum crucible and heated till they soften. The temperature is then progressively diminished, allowing the BBO crystal to form above numerous weeks. The crystal is then extracted, Minimize into the desired shape, and polished to attain a large-high-quality optical surface area.
Here you can post queries and feedback. So far as they get acknowledged by the creator, they are going to surface previously mentioned this paragraph along with the writer’s respond to. The writer will determine acceptance based on specific standards. In essence, The problem have to be of adequately wide curiosity.
As well as their significant harm threshold, BBO more info crystals also show fantastic thermal and chemical balance. They will endure a wide range of temperatures and resist degradation from different chemical interactions.
Optical parametric amplification (OPA): We use OPA to evaluate our parts�?nonlinear conversion general performance and section-matching angle for just a delivered enter wavelength and sign/idler wavelengths. We assurance that our solutions meet up with the specs for OPA apps.
