Crylink is undoubtedly an open up System, just as our mission is to connect price, Crylink believes that every man or woman and every enterprise has distinctive worth, and we hope to attach with valuable you to deliver price and reflect worth with each other.
Hello there, thank you for getting in contact with Thorlabs. The wavelength ranges in the antireflective coatings on these β-BBO crystals align with the respective wavelength bands that these crystals are optimized for. Requests for customizations is usually made by reaching out to us at techsupport@thorlabs.com
Their large damage threshold and superb thermal steadiness make them suited to use in high-electric power laser techniques, though their broad transparency vary allows them to work that has a broad choice of laser wavelengths.
Thorlabs expresses LIDT for CW lasers as a linear power density measured in W/cm. In this particular routine, the LIDT presented as being a linear electric power density might be placed on any beam diameter; just one won't should compute an modified LIDT to regulate for improvements in spot measurement, as shown via the graph to the correct. Normal linear power density might be calculated using the equation below.
Delving further in the prowess of BBO crystals, it’s evident they depict the forefront of contemporary photonics. Their broad transparency assortment not only bestows them with versatility but additionally guarantees that they are compatible with numerous gentle sources.
Yes, BBO crystals may be custom made In keeping with precise necessities. This consists of tailor made dimensions, designs, and coatings. However, customization may perhaps have an effect on the crystal’s Houses and performance, so it ought to be carried out by a professional. Personalized sizes and designs is usually Reduce from a larger BBO crystal to suit particular programs.
The 2nd harmonic frequency wave is created as an extraordinary wave, and that is polarized orthogonal to the elemental-frequency everyday wave.
Beta Barium Borate (BBO) crystals have been a subject of fascination in the field of optics and photonics because of their distinctive Houses. In the following paragraphs, we intention to reply 10 popular questions on BBO crystals, delivering a comprehensive idea of this intriguing content.
We also layer our products with anti-reflection layers to minimize illustration losses with the crystal surfaces.
If you don't locate the acceptable products and solutions above, you could let us know your requirements or applications in the shape down below. Our profits or complex team can get back to you personally without delay.
Newlight's BBO crystals are broadly Employed in next, third, fourth or fifth harmonic generations for high ability seen/UV sources, and optical parametric conversions for prime energy broadly tunable resources.
In frequency conversion, BBO crystals are accustomed to change the colour of laser light, enabling the manufacture of a wide range of colors that are not right available from out there laser resources. In electro-optic modulation, They may be applied to manage the intensity, stage, polarization, or path of a laser beam.
Any contamination can degrade the optical efficiency with the crystal and likely trigger harm under substantial laser ability. When storing BBO crystals, they should be placed within a protective situation to avoid Bodily problems and mud accumulation.
Humidity can cause drinking water absorption on the crystal floor, which might degrade its optical overall performance. The standard of the incident mild, including its wavelength, depth, and polarization, may also have more info an affect on the functionality of BBO crystals in numerous apps.
