The level of the solvent can be adjusted for various crystal dimension Therefore the lens tissue is stored moist for the entire drag but there's not any visible trace of solvent to the crystal surface once the drag is concluded. Inspect the surface area and repeat if important, but only use Each and every sheet of lens tissue as soon as.
A2: Sure, extended exposure to humidity can degrade the optical performance of BBO crystals. Humidity can cause drinking water absorption to the crystal floor, which might affect its optical Attributes.
Thorlabs provides a big variety of optics optimized for use with femtosecond and picosecond laser pulses. You should see beneath for more information.
Now compare the maximum energy density to that which happens to be specified as being the LIDT for your optic. In case the optic was tested in a wavelength aside from your functioning wavelength, the injury threshold must be scaled properly [3].
Hygroscopic crystal resources deteriorate when they are not generally held in sufficiently dry air (or perhaps a dry purge gas). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It may be practical to help keep this type of crystal at a rather elevated temperature, which makes it simpler to retain it dry.
If the crystal surfaces remain “dirty�?after the above mentioned cleaning treatments, the surfaces might need been harmed. Be sure to contact us for rework from the crystals.
β-BBO Crystal—a broadly used nonlinear crystal for frequency conversion within the ultraviolet, seen and near-infrared
Beta Barium Borate (BBO) crystals have already been a subject of desire in the sphere of optics and photonics due to their distinctive Homes. In this post, we goal to answer 10 typical questions about BBO crystals, providing an extensive idea of this fascinating product.
A5: Indeed, BBO crystals have fantastic thermal stability and may retain their Homes at place temperature. This means that they can be Utilized in an array of environments without the need of necessitating Particular temperature Regulate.
GWU-Lasertechnik provides all conventional nonlinear crystals like LBO, BBO and KTP with a wide range of technical specs. Beside the effectively-established materials, progressive crystals like CLBO or BiBO with remarkable Homes for e. g. deep-UV website generation or superior-energy ultrashort pulse lasers can be found. Irrespective of if individual parts for R & D functions are needed or Price-economical quantities in smaller, medium or substantial batches with in-time shipping and delivery for the creation line are required: GWU’s devoted service helps to discover the greatest Main elements for the software.
Irrespective of whether it’s in the event of much more efficient lasers, the exploration of quantum phenomena, or maybe the generation of recent optical products, BBO crystals will unquestionably carry on to play a pivotal function.
The posture in the environmentally friendly curve depends upon θ. In this case, the angle θ has actually been tuned to supply a refractive index for 515 nm mild that matches the refractive index for 1030 nm gentle. This tuning angle is for that reason optimized for Kind-I SHG period matching and also a fundamental-frequency input beam of 1030 nm.
BBO crystals also have a superior problems threshold, that means they're able to endure superior amounts of laser electrical power with out suffering problems. This is especially critical in applications involving substantial-power lasers. Also, BBO crystals Have got a large nonlinear coefficient, which allows successful frequency conversion, a vital functionality in several optical methods.
The size in the SHG crystal noticeably impacts the spectral width with the reference pulse, or alternatively the bandwidth with the SHG filter.
