Each wide-bandwidth pulses and temporal stroll-off induce a reduction from the conversion efficiency, along with worsen the optical quality of the next harmonic pulses. The appropriate crystal thickness needs to be chosen to attenuate each outcomes.
Hello there, thanks for getting in contact with Thorlabs. The wavelength ranges with the antireflective coatings on these β-BBO crystals align Together with the respective wavelength bands that these crystals are optimized for. Requests for customizations can be produced by achieving out to us at techsupport@thorlabs.com
Their significant harm threshold and fantastic thermal steadiness make them ideal for use in high-electrical power laser methods, even though their huge transparency assortment permits them to operate using a wide selection of laser wavelengths.
Crystal life time can even be strongly dependent on the material high-quality, Whilst selected degradation phenomena seem like intrinsic constraints of the fabric.
Delving further into your prowess of BBO crystals, it’s obvious that they signify the forefront of contemporary photonics. Their wide transparency variety not only bestows them with flexibility but in addition ensures that they're compatible with various light-weight resources.
). This spatial concentrating constraint over the SHG process will typically end in the crystal duration always being a lot less than the Rayleigh selection of the enter concentrated pulse.
The next harmonic frequency wave is produced as an extraordinary wave, that is polarized orthogonal to the basic-frequency everyday wave.
Beta Barium Borate (BBO) crystals happen to be a topic of fascination in the sphere of optics and photonics due to their special Attributes. In the following paragraphs, we purpose to answer ten prevalent questions about BBO crystals, furnishing an extensive knowledge of this fascinating product.
A5: Sure, BBO crystals have great thermal steadiness and may retain their Qualities at place temperature. Consequently they can be used in a wide range of environments with out necessitating Unique temperature control.
Any scratches can degrade the optical overall performance with the website crystal and potentially bring about destruction below significant laser power. For stubborn stains, an answer of mild detergent or isopropyl Alcoholic beverages may be Carefully applied to the crystal floor and afterwards rinsed off with distilled water.
The Uncooked products, generally a mixture of barium carbonate and boric acid, are put in a very platinum crucible and heated until finally they soften. The temperature is then little by little lowered, making it possible for the BBO crystal to kind about various weeks. The crystal is then extracted, Minimize into the desired shape, and polished to achieve a superior-top quality optical floor.
Also, BBO crystals may also be recognized for their superior nonlinear coefficient, which allows them to efficiently transform the frequency of light.
BBO crystals must be dealt with with care to stay away from scratching or detrimental their surfaces. They should be saved within a dry, neat spot and stored clear of immediate sunlight. Normal cleansing which has a tender cloth or air blower is suggested to take care of their optical general performance. When dealing with BBO crystals, it’s crucial that you use gloves to prevent oils in the pores and skin from contaminating the crystal area.
flux-grown KTP and RTP with its substantial nonlinearity, also in variants with higher grey monitoring resistance
