Sometimes, the mismatch might be little. As an example, any time a β-BBO crystal is utilized to frequency double 1550 nm gentle and provide 775 nm light, the group velocity mismatch is only some femtoseconds per millimeter.
With good care and maintenance, BBO crystals can past for a few years. Regular cleaning and good storage may also help prolong the lifespan in the crystals. Furthermore, utilizing the crystals within their specified operating parameters can also assist avoid premature degradation.
A1: Yes, BBO crystals Use a substantial damage threshold, creating them appropriate for substantial-electricity laser programs. Their skill to resist significant laser intensities with out suffering from optical harm would make them an outstanding choice for frequency conversion in higher-electrical power lasers.
Crystal life span can be strongly dependent on the material excellent, While certain degradation phenomena look like intrinsic constraints of the material.
BBO is of individual value while in the obvious and far UV. A wide variety of section-matching programs are doable, such as the following:
Standard cleaning and proper storage may help increase the lifespan of BBO crystals. It’s also important to stay clear of exposing the crystals to disorders exterior their specified functioning range, as this might cause long lasting destruction.
Filters down below or the shape at the bottom can be utilized to assist product search or make additional inquiries.
In summary, BBO crystals are a fascinating and multipurpose substance that has considerably advanced the field of optics and photonics. By being familiar with their Qualities and how to deal with them, we are able to continue on to harness their possible and travel even more improvements in optical technology.
We also layer our things with anti-reflection levels to lower representation losses for the crystal surfaces.
To stop this, BBO crystals must be saved in a dry environment and adequately sealed when not in use. Also, any cleansing course of action must be followed by complete drying to remove any residual humidity.
Large nonlinear coefficients: BBO crystals have sizeable get more info nonlinear coefficients that make effective frequency conversion procedures with small input electrical power calls for probable.
They also have a large hurt threshold, enabling them to handle superior-electric power laser beams devoid of degradation. These exclusive Qualities make BBO crystals a flexible Resource in a variety of optical programs.
Any contamination can degrade the optical overall performance from the crystal and probably lead to problems under large laser power. When storing BBO crystals, they must be placed in the protective case to forestall physical destruction and mud accumulation.
Optical parametric amplification (OPA): We use OPA to measure our parts�?nonlinear conversion efficiency and stage-matching angle for any offered enter wavelength and sign/idler wavelengths. We assurance that our items fulfill the specs for OPA apps.
