The quantity of the solvent could be adjusted for a variety of crystal sizing so the lens tissue is saved damp for the whole drag but there is not any visible trace of solvent over the crystal surface area once the drag is concluded. Inspect the surface and repeat if essential, but only use each sheet of lens tissue as soon as.
Howdy, thanks for calling Thorlabs. The wavelength ranges of the antireflective coatings on these β-BBO crystals align While using the respective wavelength bands that these crystals are optimized for. Requests for customizations could be produced by achieving out to us at [email protected]
We minimized our boule into lesser merchandise according to client specs employing a ruby blade, or twine saw equipment. After that, polish these pieces working with ruby powder or slurry on cast iron or copper plates.
Now Evaluate the utmost Vitality density to that and that is specified since the LIDT for the optic. If your optic was tested in a wavelength other than your functioning wavelength, the hurt threshold have to be scaled properly [three].
BBO is of distinct great importance inside the visible and much UV. A wide variety of period-matching apps are feasible, including the subsequent:
Beta-Barium Borate, often known as BBO crystals, are a novel form of nonlinear optical crystal that have attained important recognition in the sector of optics and photonics. These crystals are renowned for his or her extensive transparency vary, which extends in the ultraviolet towards the near-infrared spectrum.
Even so, it’s vital that you Take note that whilst BBO crystals can cope with substantial power, they ought to even now be employed inside their specified electricity selection to circumvent potential harm and ensure optimal functionality.
Cleansing BBO crystals is a delicate process that requires treatment to stop harmful the crystal’s surface. A comfortable cloth or lens tissue moistened that has a mild solvent, such as isopropyl alcohol, can be employed to gently wipe the area of your crystal.
The superior injury threshold of BBO crystals is especially vital in environments the place substantial-intensity lasers are the norm. Common components may well falter, degrade, or maybe break under these types of intensities.
It’s like taking a single note and splitting it into two harmonious tones. This method could be vital in many advanced optical experiments and systems.
Regardless of whether it’s in the event of additional efficient lasers, the exploration of quantum phenomena, or perhaps the creation of latest optical equipment, BBO crystals will unquestionably keep on to Enjoy a pivotal role.
Having said that, in several instances, the difference in the basic and check here 2nd harmonic pulse velocities can result in one particular pulse to significantly lag another.
Therefore, the next harmonic pulse spectrum, shown on the appropriate, features a spectral width somewhere around the same as The perfect case. Preferably, every single frequency in the fundamental pulse spectrum might be simultaneously stage matched.
Although the crystal content or coating just isn't sensitive to water, modest water droplets could aim laser radiation a lot more tightly than beneath typical Procedure, and thus damage the crystal content.
