Nevertheless, in many conditions, the main difference in the elemental and 2nd harmonic pulse velocities could cause just one pulse to drastically lag another.
Hello, 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 may be made by achieving out to us at techsupport@thorlabs.com
Even so, to totally utilize the potential of BBO crystals, it really is critical to be familiar with their Houses and how to take care of and retailer them correctly. These crystals demand very careful handling to forestall damage to their surfaces and may be stored in a very dry, neat area to keep up their optical efficiency.
The 266nm era makes certain that these interactions are finely tuned, making it possible for scientists to glean insights with enhanced precision. No matter if it’s in learning elaborate molecules, figuring out the Homes of recent components, or in environmental monitoring, the BBO crystal’s capacity to generate 266nm gentle amplifies the depth and precision of spectroscopic scientific studies.
In the event the Rayleigh variety is fewer than the crystal thickness, the space around which the beam is optimally extreme is below the crystal thickness.
Their large damage threshold and exceptional thermal security make them suited to use in significant-electrical power laser methods, although their extensive transparency selection enables them to work having a broad number of laser wavelengths.
These Qualities make BBO crystals highly fascinating in different applications, from laser frequency conversion to electro-optic modulation. Their large transparency assortment enables them to operate using a wide variety of laser wavelengths, whilst their superior harm threshold makes sure they're able to handle significant-energy laser beams without the need of degradation.
Comprehension Crystal is akin to appreciating the bedrock of State-of-the-art optical technological know-how. At its essence, BBO, or Beta Barium Borate, stands like a nonlinear optical crystal. The term “nonlinear�?here signifies the exclusive potential on the crystal to interact with light in a fashion that alters The sunshine’s frequency.
A5: Certainly, BBO crystals have excellent thermal balance and might maintain their Homes at home temperature. Because of this they may be Employed in an array of environments devoid of demanding special temperature get more info Regulate.
Just about every side of BBO, from its atomic construction to its wide application spectrum, underscores its pivotal purpose in modern day science and technological know-how.
When selecting an SHG crystal, the heart beat duration in the laser resource must be taken into consideration. A mismatch amongst the period and crystal thickness will result in SHG pulses extended in time and narrower in spectral content than achievable beneath great conditions.
Nonetheless, the nonlinear optical Homes of the-BBO crystal is vanished mainly because of the centric symmetry with its crystal structure. It isn't encouraged to employ for NLO procedures.
Also, the structural and compositional attributes of BBO supply it with exceptional thermal stability and resistance from environmental issues.
