The 266nm wavelength delivers precise interactions that other wavelengths can’t, making it indispensable for detecting and studying specific compounds.

Any scratches can degrade the optical overall performance of the crystal and possibly result in harm under higher laser power. For stubborn stains, an answer of delicate detergent or isopropyl alcohol may be gently placed on the crystal surface area after which you can rinsed off with distilled h2o.

This effectiveness is significant, particularly when a person considers the era of the 266nm wavelength, in which even minor inefficiencies may lead to considerable Electrical power losses.

We use Numerical Aperture (NA) to describe the extent of the angular content material. Preferably, the fundamental laser light can be collimated throughout the crystal, considering that collimated light-weight resembles a group of rays aligned to precisely the same way using an NA of zero.

However, it’s crucial that you Take note that although BBO crystals can transmit UV gentle, they should be dealt with with care when Utilized in UV purposes to prevent possible harm to the crystal and guarantee protection.

Although the examination outcomes are only consultant of 1 coating run, Thorlabs specifies damage threshold values that account for coating variances.

This precision permits the fabrication of intricate buildings and styles on several materials, from metals to biological tissues. It’s not almost making more compact objects; it’s about creating them with the unparalleled volume of depth.

Now Look at the most Electrical power density to that that is specified since the LIDT for the optic. If the optic was examined in a wavelength in addition to your functioning wavelength, the injury threshold has to be scaled properly [three].

It’s like having a single Notice and splitting it into two harmonious tones. This method may be important in a lot of Highly developed optical experiments and systems.

Filters beneath or the shape at The underside may be used to assist product look for or make further more inquiries.

Custom made coatings could be applied to the crystal surfaces to boost their functionality at precise wavelengths or to shield the crystal from environmental variables. On the other hand, it’s imperative that you Take note that any customization ought to be carried out cautiously in order to avoid degrading the crystal’s optical Homes.

When click here an enter pulse's spectral selection is equivalent to or narrower when compared to the reference pulse, the created next harmonic pulse has a period that may be shorter by an element of one/√2 as well as a spectral width which is broader by a factor of √two.

The spectrally narrowed SHG pulse spectrum is alleged for being apodized, due to the fact an effect of the basic pulse exceeding the utmost enter bandwidth limit would be the removing of the best and lowest frequencies from the SHG pulse spectrum.
