The crystal axis is c. The Main ray is parallel on the direction accustomed to evaluate the tuning angle (θ), which happens to be optimized during phase matching. Conversion performance is optimized for rays parallel towards the Main ray and worse for rays at larger sized angles (ψ) into the chief ray.

This kind of resilience makes sure that its nonlinear Attributes usually are not easily compromised, which makes it a favourite in environments where consistency and dependability are paramount.

Any scratches can degrade the optical overall performance of your crystal and likely result in harm underneath significant laser electricity. For stubborn stains, an answer of delicate detergent or isopropyl Alcoholic beverages can be Carefully applied to the crystal surface then rinsed off with distilled drinking water.

When just one of these β-BBO Crystals is mounted while in the RSP1 mount, the crystal will probably be centered around the 8-32 (M4) hole during the mount's base without the have to have for spacers.

We use Numerical Aperture (NA) to explain the extent of this angular content. Ideally, the elemental laser mild would be collimated through the entire crystal, due to the fact collimated light-weight resembles a bunch of rays aligned to precisely the same way having an NA of zero.

Nonetheless, it’s essential to note that even though BBO crystals can transmit UV gentle, they must be handled with care when used in UV apps to avoid prospective harm to the crystal and assure protection.

Although the test final results are only consultant of one coating operate, Thorlabs specifies hurt threshold values that account for coating variances.

This precision permits the fabrication of intricate buildings and patterns on different elements, from metals to Organic tissues. It’s not pretty much creating smaller sized objects; it’s about producing them by having an unparalleled volume of depth.

Now Review the most Power density to that click here that is specified since the LIDT for that optic. When the optic was tested at a wavelength aside from your operating wavelength, the problems threshold needs to be scaled appropriately [three].

A5: Yes, BBO crystals have outstanding thermal security and will manage their Qualities at space temperature. Consequently they may be used in an array of environments with no necessitating Distinctive temperature control.

Both broad-bandwidth pulses and temporal stroll-off lead to a discount in the conversion efficiency, and also worsen the optical excellent of the 2nd harmonic pulses. The right crystal thickness ought to be picked to reduce equally outcomes.

Certainly, BBO crystals may be custom-made In keeping with particular demands. This incorporates custom sizes, shapes, and coatings. Even so, customization may well affect the crystal’s Attributes and overall performance, so it should be completed by an experienced. Personalized measurements and designs is often Slice from a bigger BBO crystal to suit precise apps.

The 266nm era refers back to the manufacture of ultraviolet mild which has a wavelength of 266 nanometers.

Furthermore, the structural and compositional characteristics of BBO give it with impressive thermal steadiness and resistance from environmental problems.
