The large destruction threshold of BBO crystals is particularly critical in environments where by higher-depth lasers would be the norm. Common products may well falter, degrade, or simply break underneath this kind of intensities.
Sadly, it might be quite challenging to compare the LIDT specification of an optic towards your laser. You can find many regimes in which a pulsed laser can injury an optic and this is based on the laser's pulse duration. The highlighted columns within the desk under outline the pertinent pulse lengths for our specified LIDT values.
Hi there, thank you for speaking to Thorlabs. The wavelength ranges from the antireflective coatings on these β-BBO crystals align with the respective wavelength bands that these crystals are optimized for. Requests for customizations can be made by achieving out to us at techsupport@thorlabs.com
However, it’s crucial that you Take note that although BBO crystals can manage superior energy, they should continue to be used within just their specified electric power range to prevent possible destruction and ensure optimal effectiveness.
Finally, the extensive-angle tunability of BBOs facilitates customization like under no circumstances prior to. Depending upon the specific necessities of an software, the crystal might be modified with precision, ensuring which the output is always optimized.
Provided these applications, it’s obvious why BBO, with its inherent capability to effectively produce the 266nm wavelength, is so highly prized. The crystal’s exclusive nonlinear optical Homes empower the conversion of other wavelengths in the coveted 266nm gentle, ensuring that researchers and industries have access to this crucial Device.
Delving deeper to the prowess of BBO crystals, it’s apparent which they signify the forefront of contemporary photonics. Their broad transparency assortment don't just bestows them with versatility but will also makes sure that they're suitable with numerous gentle sources.
a-BBO crystals having a wedge angle (α) could be custom fabricated with the required orientation in the optical axis. A paired or these prisms While using the optical axes orthogonal to each other can be employed to consistently change the period shift or time hold off concerning two orthogonally polarized pulses.
This residence sets it apart from linear optical materials that don’t alter the frequency of light passing through them. This type of distinguishing function varieties the muse for any plethora of programs that BBO can serve.
The period velocity is the rate at which the field provider, i.e. the sine wave, travels in a material. The speed at which a pulse envelope travels in a cloth is known as the team velocity and defines the velocity in the energy packet comprising the optical pulse traveling through the fabric.
BBO crystals, with their one of a kind properties and big selection of apps, have grown to be a cornerstone in the sphere of optics and photonics. These crystals, noted for their vast transparency variety, significant problems threshold, and superb non-linear optical Attributes, have revolutionized the best way we manipulate light, opening up new options in many scientific and technological fields.
When comparing an LIDT specified for your pulsed laser to your laser, it is essential to be aware of the following:
Having said that, the nonlinear optical Houses of the-BBO crystal is vanished mainly because of the centric symmetry with its crystal structure. It isn't recommended to work with here for NLO processes.
Era of deep ultraviolet radiation at 210 nm by Form-I third harmonic technology is obtained in a very pair of BBO crystals with conversion performance as high as 36%.
