Hello, thanks for making contact with Thorlabs. The wavelength ranges of the antireflective coatings on these β-BBO crystals align With all the respective wavelength bands that these crystals are optimized for. Requests for customizations is usually produced by achieving out to us at [email protected]
Their large destruction threshold and fantastic thermal security make them appropriate for use in substantial-ability laser systems, while their wide transparency assortment enables them to operate with a wide range of laser wavelengths.
Sure, BBO crystals might be customized to satisfy distinct requirements. This includes customized dimensions, shapes, and coatings. Personalized measurements and styles can be Slash to fit particular optical methods, although custom coatings is often applied to enrich the crystal’s overall performance in particular purposes.
Normally, the crystal content should have a substantial optical transparency for all wavelengths included �?for example, for pump, sign and idler in an optical parametric amplifier.
They show excellent homogeneity over substantial volumes and have a significant harm threshold, but are hygroscopic and possess a low nonlinearity.
When laser gentle is targeted to a place, the diameter from the beam midsection would be the focal location measurement, and the speed at which the light diverges within the beam waist is relevant to the Rayleigh variety (zR).
Beta Barium Borate (BBO) crystals are actually a subject of fascination in the field of optics and photonics because of their unique Homes. On this page, we purpose to reply 10 popular questions on BBO crystals, giving an extensive comprehension of this fascinating materials.
Making use of our advertising and marketing package, you can Exhibit your brand, additional below your product or service description, and these will been viewed by a lot of photonics industry experts.
As opposed to decompose the SHG polarization into components Ex and Ez, the light is typically called a rare wave (E'e) using a refractive index, n'e. Inside the diagram on the appropriate, n'e, which is determined by θ, is indicated via the intersection of the conic part illustrated through the red ellipse Along with the XZ plane.
As Beforehand said, pulsed lasers ordinarily induce a distinct type of harm to your optic than CW lasers. Pulsed lasers usually never heat the optic adequate to break it; as a substitute, pulsed lasers produce robust electrical fields effective at inducing dielectric breakdown in the fabric.
rystal surface is horizontal and marginally earlier mentioned your fingers. Take a clean, cleanse sheet of lens tissue and spot it within the crystal. Be sure the lens tissue might be drawn over the crystal surface area. Up coming, location a small fall of pure isopropyl Liquor (IPA) within the lens tissue in addition to the crystal floor.
In the case of ultrashort pulses the significant team velocity mismatch enforces the usage of a shorter crystal, which involves significant optical intensities for just a specified conversion performance.
Humidity can result in drinking water absorption to the crystal surface area, which often can degrade its optical performance. The caliber of the incident light, which include its wavelength, depth, get more info and polarization, also can have an affect on the functionality of BBO crystals in various programs.
