Optical parametric oscillation (OPO): We employ OPO to ascertain our merchandise�?nonlinear conversion functionality and stage-matching angle for any supplied enter wavelength and signal/idler wavelengths. We make specific that our goods fulfill the requirements for OPO apps.
Whilst the above technique presents a fantastic general guideline for LIDT values, make sure you Make contact with Tech Aid In the event your wavelength is different from the specified LIDT wavelength. If your electrical power density is less than the modified LIDT in the optic, then the optic must do the job to your application.
We lessened our boule into scaled-down goods In line with customer technical specs utilizing a ruby blade, or wire noticed machine. After that, polish these pieces utilizing ruby powder or slurry on Forged iron or copper plates.
Take note that even if the nominal intensity is under the nominal injury threshold, there might be difficulties due to fluctuations in the beam electrical power or neighborhood intensity (e.g., if a beam profile has “very hot places�?, or due to isolated defects inside of a crystal, which can be additional delicate than the typical crystal content.
Even nicely down below the brink for immediate problems, some crystal resources show a continuous degradation inside the utilised volume, e.
These kinds of resilience ensures that its nonlinear Attributes are usually not easily compromised, making it a favorite in environments where by consistency and trustworthiness are paramount.
Filters under or the form at the bottom can be employed to aid solution research or make further more inquiries.
We also gauge the improved pulses�?temporal pulse form and spectral transmission capacity. We Make certain that our products and solutions fulfill the necessities for OPCPA applications.
In summation, while many crystals provide unique benefits while in the realm of photonics, BBO crystals arise as extensive powerhouses. They encapsulate A selection of capabilities that are not just advantageous in isolation but do the job synergistically, creating a holistic Resolution for frequency doubling and harmonics era.
The Electrical power density within your beam need to be calculated in terms of J/cm2. The graph to the appropriate displays why expressing the LIDT being an Vitality density gives the best metric for brief pulse resources. In this particular routine, the LIDT specified as an Electricity density may be applied to any beam diameter; 1 won't have to compute an modified LIDT to regulate for adjustments in place size.
These crystals are unique because of their ability to change the frequency of light passing by means of them, a assets that is extremely desired in a variety of fields like laser technologies and quantum physics. The flexibility of BBO crystals would make them a vital component in lots of Highly developed optical programs.
BBO nonlinear crystal is a negative uniaxial crystal. It offers phase matching for many 2nd-get interactions Virtually over its total transparency range. This transparency ranges from 185 nm to 3.3 µm, as inferred from transmittance measurements applying crystal samples of some mm thickness.
GWU-Lasertechnik has greater than thirty decades of practical experience in distributing laser crystals. Opt for GWU to take advantage of our broad awareness and in-area experience!
Even more info if the crystal content or coating is not really delicate to h2o, little water droplets may aim laser radiation extra tightly than underneath usual operation, and thus harm the crystal materials.
