Sometimes, the mismatch might be little. As an example, every time a β-BBO crystal is utilized to frequency double 1550 nm gentle and provide 775 nm mild, the group velocity mismatch is only some femtoseconds for every millimeter.

The choice of the best suited crystal product for any specified application is often significantly from trivial; it ought to require the thing to consider of many features. For example, a large nonlinearity for frequency conversion of ultrashort pulses doesn't support When the interaction size is strongly limited by a sizable group velocity mismatch as well as low injury threshold limits the applicable optical intensities.

The temporal stroll-off with the slower pulse with regard into the more quickly may be a substantial portion of the heart beat length. This really is illustrated in Figure 22.

BBO crystals can be bought from different suppliers specializing in optical supplies. It’s vital that you opt for a highly regarded provider to make sure the standard of the crystals.

For beams having a superior PRF each the common and peak powers need to be when compared with the equal CW electricity. On top of that, for hugely clear components, There is certainly very little to no drop in the LIDT with increasing PRF.

If the crystal surfaces are still “dirty�?just after the above cleaning techniques, the surfaces may need been weakened. Please contact us for rework with the crystals.

β-BBO Crystal—a widely used nonlinear crystal for frequency conversion inside the ultraviolet, seen and close to-infrared

Beta Barium Borate (BBO) crystals are a subject of desire in the sector of optics and photonics because of their distinctive Homes. On this page, we intention to reply 10 prevalent questions on BBO crystals, delivering a comprehensive idea of this fascinating material.

A5: Sure, BBO crystals have superb thermal balance and might sustain their Houses at area temperature. Therefore they can be used in a variety of environments with no requiring Specific temperature Manage.

For example, anti-reflective coatings can be placed on decrease light-weight loss because of reflection, whilst protective coatings can be employed to increase the crystal’s resistance to environmental variables. Customization permits ideal general performance in distinct applications.

Hi, I had been questioning if It can be doable to suit your needs to supply a BBO crystal with a personalized coating at 532nm fundamental and 266nm next harmonic generation. Finest, Ben

The position from the green curve will depend on θ. In this instance, the angle θ has become tuned to deliver a refractive index for 515 nm light that matches the refractive index for 1030 nm light. This tuning angle is therefore optimized for Type-I SHG section matching in addition to a basic-frequency input beam of 1030 nm.

Any contamination can degrade the optical performance on the crystal and most likely cause harm beneath significant laser electrical power. When storing BBO crystals, they should be positioned inside of a protective read more situation to stop Bodily destruction and dust accumulation.

When picking a supplier, look at factors like the provider’s experience, merchandise high-quality, customer service, and pricing. It’s also a smart idea to ask for a sample or maybe a test report to validate the standard of the crystals before making a acquire.
