Optical parametric oscillation (OPO): We make use of OPO to ascertain our objects�?nonlinear conversion functionality and phase-matching angle for a given input wavelength and signal/idler wavelengths. We make specified that our items satisfy the requirements for OPO applications.
Howdy, thank you for calling Thorlabs. The wavelength ranges of your antireflective coatings on these β-BBO crystals align Using the respective wavelength bands that these crystals are optimized for. Requests for customizations is usually produced by reaching out to us at techsupport@thorlabs.com
Thorlabs offers a big choice of optics optimized for use with femtosecond and picosecond laser pulses. Make sure you see underneath For more info.
Quantum optics: BBO crystals serve for quantum optical experiments such as knotted photon pair era, quantum condition tomography, quantum cryptography, and quantum assessment.
Wide openness variety: BBO crystals have a large openness array from 189 nm to 3500 nm, masking ultraviolet, seen, and close to-infrared locations. This allows BBO crystals for use for numerous laser resources with numerous wavelengths.
Superior destruction threshold: BBO crystals have higher hurt restrictions that can arise for their superior top rated and usual electricity devoid of degradation or damage.
β-BBO Crystal—a widely applied nonlinear crystal for frequency conversion inside the ultraviolet, noticeable and near-infrared
This special combination ensures that β-BBO crystal is actually a promising prospect for nonlinear optical applications which include frequency converters and optical parametric oscillators. In quantum optics, β-BBO crystal can make entangled photon pairs and 10-photon entanglement.
The group velocities of the basic and 2nd harmonic pulses are unique, even when section-matched, and the magnitude from the team velocity mismatch is dependent upon the crystal Houses and the optical frequencies in the pulses.
BBO crystals could be purchased from several different suppliers worldwide. When picking a provider, it’s crucial to take into account variables such as the quality of the crystals, the supplier’s track record, and the extent of customer care supplied.
The four decreased figures illustrate the team velocity delay (temporal walk-off) boosts given that the pulses propagate through the material. The temporal stroll-off is illustrated for distances Z0 as a result of Z3, which can be indicated BBO Crystal over the diagram at major.
The spectrally narrowed SHG pulse spectrum is alleged for being apodized, considering that an impact of the elemental pulse exceeding the utmost enter bandwidth limit will be the elimination of the highest and least expensive frequencies from your SHG pulse spectrum.
3rd harmonic era (THG): We use THG to measure our pieces�?nonlinear conversion success and period-matching angle to get a provided input wavelength. We make sure that our products and solutions fulfill the specs for THG applications.
At last, the Minimize crystals are polished to some clean finish. This sprucing method not simply improves the aesthetic physical appearance of the crystals and also improves their optical Homes by lessening surface area imperfections.
