Optical parametric oscillation (OPO): We employ OPO to find out our products�?nonlinear conversion efficiency and stage-matching angle for a provided input wavelength and sign/idler wavelengths. We make specified that our products fulfill the requirements for OPO programs.
g. in the form of “gray tracking�? These types of phenomena are specifically typical for operation with ultraviolet gentle. Take note that a gradual degradation might also guide into immediate catastrophic harm by means of extreme heat era.
We decreased our boule into scaled-down products according to client specs using a ruby blade, or twine observed device. After that, polish these pieces using ruby powder or slurry on Solid iron or copper plates.
Sure, BBO crystals can be customized to meet precise demands. This incorporates custom made dimensions, styles, and coatings. Tailor made dimensions and shapes might be Reduce to suit precise optical units, though custom made coatings is usually placed on enhance the crystal’s functionality in certain applications.
The seed crystal is a little bit BBO crystal with a definite positioning together certainly one of its principal axes. The seed crystal is affixed to some turning rod that dips into your thaw surface area space.
Beta-Barium Borate, also referred to as BBO crystals, are a singular form of nonlinear optical crystal which have gained considerable recognition in the sector of optics and photonics. These crystals are renowned for their comprehensive transparency vary, which extends with the ultraviolet into the in close proximity to-infrared spectrum.
However, it’s essential to Be aware that even though BBO crystals can deal with high energy, they ought to nonetheless be utilised inside their specified electricity selection to prevent potential hurt and be certain exceptional efficiency.
When pulse lengths are involving 1 ns and 1 µs, laser-induced injury can occur both as a result of absorption or a dielectric breakdown (hence, a user must Test both CW and pulsed LIDT). Absorption is both due to an intrinsic residence of your optic or resulting from floor irregularities; thus LIDT values are only valid for optics Assembly or exceeding the area top quality specifications supplied by a company.
This calculation assumes a uniform beam depth profile. You have to now alter this Electricity density to account for hotspots or other nonuniform depth profiles and approximately determine a greatest Electrical power density. For reference a Gaussian beam commonly contains a most energy density that is certainly two times that with the 1/e2 beam.
The section matching angle may be adjusted by rotating the crystal around the y axis. An adjustment that is usually inside of a couple of degrees can possibly optimize the performance in the crystal during the set up or match One more fundamental frequency during the crystal's operating array.
Hello, I used to be questioning if It really is possible in your case to create a BBO crystal by using a custom made coating at 532nm basic and 266nm second harmonic era. Very best, Ben
rystal area is horizontal and marginally above your fingers. Take a new, clear sheet of lens tissue and area it within the crystal. Be certain the lens tissue might be drawn throughout the crystal surface area. Future, spot a small drop of pure isopropyl Liquor (IPA) about the lens tissue along with the crystal surface.
The 266nm technology refers back to the production of ultraviolet gentle by using a wavelength of 266 nanometers.
Our crystals are Utilized in a wide range of purposes, which include several kinds of nonlinear frequency get more info conversion and electro-optics, and also quantum technology.
