The calculation higher than assumes a uniform beam depth profile. You need to now look at hotspots within the beam or other non-uniform depth profiles and about compute a greatest energy density.
The 266nm wavelength gives particular interactions that other wavelengths can’t, which makes it indispensable for detecting and learning specified compounds.
Howdy, thank you 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 made by achieving out to us at techsupport@thorlabs.com
A: A high harm threshold ensures the crystal can cope with more electricity without the need of degrading, resulting in for a longer period lifespan and constant functionality.
BBO crystals may be cleaned employing a gentle fabric or air blower. For stubborn stains, a delicate detergent or isopropyl Liquor can be employed. It’s crucial to prevent working with abrasive elements that may scratch the crystal’s area. When cleansing BBO crystals, it’s crucial to use a mild, circular motion to avoid scratching the surface area.
Detrimental uniaxial α-BBO crystal is a superb birefringent crystal, appropriate for the manufacture of polarizer, polarization beam displacer, time delay compensator plate along with other birefringent product, especially for UV and higher ability laser.
Humidity may cause h2o absorption on the crystal surface, which may degrade its optical functionality. The quality of the incident light, together with its wavelength, intensity, and polarization, could also impact the efficiency of BBO crystals in a variety of purposes.
This type of capability is priceless in conditions exactly where a selected mild frequency is needed, though the supply doesn’t Obviously supply it. By employing BBO’s Qualities, researchers and engineers can properly “tune�?their light-weight sources to preferred frequencies.
Taken alongside one another, these various purposes underscore the immense value BBO crystals deliver to many sectors. As a result of its unparalleled 266nm technology, the BBO crystal is not merely a Resource but a catalyst, propelling developments across distinct fields.
With correct treatment and dealing with, click here BBO crystals can previous for a few years. However, their lifespan can be shortened by elements for instance significant temperature, humidity, and physical destruction. BBO crystals are strong and sturdy, but Like every optical element, they could degrade after some time Otherwise adequately cared for.
A: The wide transparency vary provides flexibility, allowing BBO crystals for use throughout a diverse array of wavelengths and purposes.
When evaluating an LIDT specified to get a pulsed laser for your laser, it is important to grasp the next:
On the other hand, the nonlinear optical Houses of a-BBO crystal is vanished due to centric symmetry with its crystal construction. It is far from advisable to make use of for NLO processes.
Generation of deep ultraviolet radiation at 210 nm by Sort-I third harmonic technology is accomplished in a very set of BBO crystals with conversion performance as higher as 36%.
