Occasionally, the mismatch may be modest. One example is, each time a β-BBO crystal is utilized to frequency double 1550 nm gentle and supply 775 nm light-weight, the group velocity mismatch is just a few femtoseconds per millimeter.

A2: Certainly, extended exposure to humidity can degrade the optical functionality of BBO crystals. Humidity can cause drinking water absorption about the crystal area, which could have an impact on its optical Homes.

If the Rayleigh array is lower than the crystal thickness, the gap above which the beam is optimally powerful is below the crystal thickness.

Quantum optics: BBO crystals serve for quantum optical experiments for example knotted photon pair era, quantum point out tomography, quantum cryptography, and quantum assessment.

Artifex Engineering presents finished crystal optics for non-linear purposes. Pay a visit to our merchandise site for more information. We anticipate your inquiry.

Many things can affect the general performance of BBO crystals. These include temperature, humidity, and the standard of the incident light-weight. Good managing and storage can help retain the crystal’s overall performance. Temperature can influence the period-matching problems of BBO crystals, which in turn affects their performance in frequency conversion applications.

There are 2 velocities that determine the propagation of sunshine in optical media: the period and group velocities. The stage velocity could be the pace with the provider, the oscillation of the electrical discipline, and the velocity which is matched amongst the basic and 2nd harmonic frequencies for period matching. The period velocity relative on the speed of light in the vacuum is defined through the index of refraction.

When pulse lengths are involving one ns and 1 µs, laser-induced hurt can manifest both due to absorption or maybe a dielectric breakdown (therefore, a consumer must check both equally CW and pulsed LIDT). Absorption is either due to an intrinsic house with the optic or as a result of floor irregularities; As a result LIDT values are only valid for optics Assembly or exceeding the area quality specs supplied by a company.

The large hurt threshold of BBO crystals is especially important in environments where by significant-intensity lasers tend to be the norm. Common resources may well falter, degrade, or even split below these types of intensities.

Other period matching disorders are feasible. Significant Kind-II section matching makes use of an oe-o or eo-e for positive and adverse uniaxial crystals. Non-important section matching uses crystal temperature to attain period matching rather than angular tuning.

This house is especially helpful in apps here that entail large-electricity lasers or intensive gentle sources, as it makes certain the longevity and dependability of the crystal in these types of demanding conditions.

The crystal axis is c. The chief ray is parallel towards the direction utilized to measure the tuning angle (θ), which can be optimized throughout section matching. Conversion effectiveness is optimized for rays parallel to your Main ray and worse for rays at bigger angles (ψ) into the chief ray.

Third harmonic generation (THG): We use THG to evaluate our items�?nonlinear conversion usefulness and phase-matching angle to get a specified input wavelength. We Guantee that our goods fulfill the specs for THG purposes.

Optical parametric amplification (OPA): We use OPA to evaluate our pieces�?nonlinear conversion functionality and period-matching angle for just a provided input wavelength and signal/idler wavelengths. We assure that our items satisfy the specs for OPA applications.
