This information dives deep into the advantages and distinctive Homes of BBO crystal and its paramount significance in economical frequency doubling and harmonics technology at 266nm.
g. in the shape of “grey tracking�? These kinds of phenomena are specially common for operation with ultraviolet gentle. Note that a gradual degradation may lead into prompt catastrophic harm by way of too much warmth era.
We minimized our boule into smaller goods In line with client requirements employing a ruby blade, or twine observed device. After that, polish these pieces employing ruby powder or slurry on cast iron or copper plates.
) is The main element for BBO to obtain substantial conversion effectiveness. Restricted aim of laser beam isn't recommended.
BBO crystals might be cleaned utilizing a gentle cloth or air blower. For stubborn stains, a moderate detergent or isopropyl Liquor can be utilized. It’s essential to avoid utilizing abrasive components that could scratch the crystal’s surface. When cleaning BBO crystals, it’s imperative that you use a gentle, round motion to stop scratching the surface.
Make sure you pick out your shipping and delivery state to watch by far the most precise inventory info, and to determine the right Edmund Optics profits Business in your order.
The reducing angle relies upon upon the popular phase-matching trouble for frequency conversion applications. Phase matching describes matching the section speeds of assorted beams linked to nonlinear processes so which they Establish up constructively above fars absent inside the crystal.
the chemical toughness; e.g., some crystal elements are hygroscopic, Other people bear chemical adjustments when heated in a vacuum chamber for application of the dielectric coating
Beam diameter is additionally important to know when comparing damage more info thresholds. When the LIDT, when expressed in units of J/cm², scales independently of location dimension; huge beam measurements usually tend to illuminate a bigger number of defects which can cause increased variances during the LIDT [4].
The phase matching angle could be adjusted by rotating the crystal around the y axis. An adjustment that is typically inside a couple of degrees can possibly improve the performance from the crystal inside the set up or match A different fundamental frequency within the crystal's working variety.
This house is particularly beneficial in purposes that require substantial-energy lasers or intense mild sources, because it guarantees the longevity and reliability of the crystal in such demanding disorders.
The crystal axis is c. The chief ray is parallel to the way accustomed to measure the tuning angle (θ), which happens to be optimized all through phase matching. Conversion performance is optimized for rays parallel to your Main ray and worse for rays at bigger angles (ψ) to the Main ray.
BBO crystals even have a substantial hurt threshold, which means they can withstand high amounts of laser electrical power with out struggling damage. This is especially critical in programs involving significant-electricity lasers. Additionally, BBO crystals Have got a large nonlinear coefficient, which enables economical frequency conversion, a crucial functionality in many optical devices.
Our crystals are Utilized in an array of applications, together with several forms of nonlinear frequency conversion and electro-optics, but additionally quantum technologies.
