A: Sure, BBO crystals exhibit extraordinary thermal stability, generating them suited to programs with different temperatures.
Although the above mentioned course of action supplies a great rule of thumb for LIDT values, remember to Get hold of Tech Support If the wavelength differs from the required LIDT wavelength. In case your power density is a lot less than the altered LIDT of the optic, then the optic need to operate on your software.
Thorlabs provides a wide selection of optics optimized for use with femtosecond and picosecond laser pulses. Remember to see beneath for more information.
Yes, BBO crystals is often personalized to meet unique prerequisites. This features custom measurements, styles, and coatings. Customized sizes and designs is often Reduce to fit unique optical programs, while custom coatings could be applied to enhance the crystal’s general performance in particular applications.
Wide openness assortment: BBO crystals have a large openness array from 189 nm to 3500 nm, masking ultraviolet, seen, and in the vicinity of-infrared regions. This enables BBO crystals for use for varied laser sources with various wavelengths.
Of course, BBO crystals could be custom made As outlined by certain necessities. This incorporates tailor made dimensions, shapes, and coatings. Nevertheless, customization may have an affect on the crystal’s Attributes and functionality, so it should be finished by knowledgeable. Custom dimensions and designs might be Lower from a larger BBO crystal to suit precise applications.

The length of the crystal is a vital parameter to take into account when optimizing the SHG procedure for the parameters of particular enter pulses. Absent period-matching and temporal walk-off consequences, the SHG output improves exponentially with crystal duration. The goal when selecting an SHG crystal should be to harmony the crystal duration with the constraints determined by the elemental pulse. Lowering the crystal thickness lessens results related to both equally period-matching bandwidth constraints and temporal stroll-off, which are instantly linked.
The group velocities of the basic and 2nd harmonic pulses will also be unique, even though phase-matched, along with the magnitude of the group velocity mismatch will depend on the crystal Attributes and the optical frequencies within the pulses.
Other phase matching conditions are also doable. Crucial Form-II section matching takes advantage of an oe-o or eo-e for constructive and adverse uniaxial crystals. read more Non-vital section matching works by using crystal temperature to obtain phase matching as an alternative to angular tuning.
Alternatively, a small enclosure (with openings for light-weight) could be built throughout the crystal which has a continual circulation of dry nitrogen of air in to the enclosure. The dry nitrogen/air stress demands only to become a little above the atmosphere to keep the smaller quantity around the crystal dry and cleanse.
Whilst the exam effects are only representative of 1 coating run, Thorlabs specifies problems threshold values that account for coating variances.
BBO crystals also have a large injury threshold, which means they are able to endure significant levels of laser energy with out struggling harm. This is particularly significant in programs involving higher-power lasers. On top of that, BBO crystals Use a substantial nonlinear coefficient, which allows economical frequency conversion, a vital function in several optical units.
One more equally intriguing application is optical parametric oscillation. On this, BBO permits the conversion of the photon into two photons with diverse frequencies, the sum of which equals the initial photon’s frequency.
