BBO Crystal - An Overview
BBO Crystal - An Overview
Blog Article
The amount of the solvent can be adjusted for various crystal dimension Hence the lens tissue is stored damp for the whole drag but there's not any visible trace of solvent within the crystal surface after the drag is concluded. Inspect the surface and repeat if required, but only use Each individual sheet of lens tissue when.
Even so, it’s vital that you Be aware that though BBO crystals can transmit UV mild, they ought to be managed with care when Utilized in UV purposes to forestall prospective damage to the crystal and guarantee basic safety.
Optical transmission (OT): We benefit from OT to measure the optical passage spectrum of our objects over their openness array. We assurance our products and solutions are devoid of absorption bands or scattering losses as a consequence of pollutants or difficulties.
Borates including LBO and BBO also operate very well in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
For beams by using a substantial PRF both of those the standard and peak powers has to be when compared with the equivalent CW energy. Moreover, for very clear elements, There's little to no fall within the LIDT with raising PRF.
Their one of a kind Attributes make them a most well-liked option for a lot of demanding and higher-precision optical apps.
This generate-up will explain how we crank out significant-high-quality BBO crystals at our organization. We will even review some advantages and difficulties of making use of BBO crystals for regularity conversion.
In conclusion, BBO crystals are a fascinating and functional product which includes significantly Innovative the sector of optics and photonics. By comprehension their Houses and the way to take care of them, we will keep on to harness their likely and push even more enhancements in optical technological know-how.
For consumer benefit the crystals could be mounted in an 1" anodized aluminum (Al) mount. The mounted crystals may be even further mounted in a standard one" mirror mount being angle tuned for stage matching (as demonstrated to the ideal). Water-cooled mounts for prime energy applications is often presented on request.
The Strength density within your beam needs to be calculated when it comes to J/cm2. The graph to the ideal demonstrates why expressing the LIDT being an Electricity density gives the best metric for brief pulse resources. In this particular regime, the LIDT presented as an Strength density is often applied to any beam diameter; just one will not need to compute an altered LIDT to regulate for improvements in spot dimensions.
Alternatively, a small enclosure (with openings for mild) might be built round the crystal using a steady flow of dry nitrogen of air into the enclosure. The dry nitrogen/air stress desires only for being a little bit above the ambiance to keep the tiny volume throughout the crystal dry and clean up.
The situation of the inexperienced curve depends upon θ. In cases like this, the angle θ continues to be tuned to supply a refractive index for 515 nm light-weight that matches the refractive index for 1030 nm light-weight. This tuning angle is consequently optimized for Type-I SHG section matching along with a fundamental-frequency input beam of 1030 nm.
And lastly, spectroscopy, the research of interactions in between issue and electromagnetic radiation, drastically Positive aspects through the 266nm technology. In spectroscopic apps, distinctive wavelengths of sunshine interact in another way with supplies, supplying a spectrum that can be analyzed to determine the fabric’s properties or composition.
Optical parametric amplification (OPA): We use OPA to evaluate our parts�?nonlinear conversion performance and section-matching angle for the delivered enter wavelength click here and sign/idler wavelengths. We warranty that our merchandise fulfill the specs for OPA apps.
