5 Essential Elements For LBO Crystal
Blog Article
They may also be useful for frequency doubling invisible 1-micron light-weight into 532nm noticeable inexperienced gentle, an software which has Formerly belonged to KTP crystals.
Pulsed solid condition UV lasers have already been investigated for building the ultrashort wavelength deep ultraviolet mild that presently arises from excimer lasers, as Employed in photolithography of semiconductor chips.
the chemical durability; e.g., some crystal materials are hygroscopic, Other folks endure chemical changes when heated in a vacuum chamber for application of a dielectric coating
Typically, the crystal substance ought to have a high optical transparency for all wavelengths involved �?one example is, for pump, sign and idler within an optical parametric amplifier.
A lot of the regular nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the elemental laser radiation are offered from inventory. Client-unique Proportions and AR coatings may also be provided at aggressive costs.
Please select your shipping country to see by far the most exact stock information and facts, and to ascertain the correct Edmund Optics revenue office for the get.
Optical microscopy can be utilized to determine floor defects, including scratches, cracks, and pits, that may have an affect on the effectiveness in the crystal in several applications. Optical microscopy will also be utilized to ascertain the crystal thickness and uniformity.
Further more enriching their optical charm is the wide acceptance angle. This feature allows for additional considerable light-weight click here interaction and minimizes the requirements for beam alignment, simplifying the general Procedure.
Optical microscopy is usually a frequently utilized procedure for characterizing the floor morphology and defects in LBO nonlinear crystals. Optical microscopy includes illuminating the crystal having a beam of sunshine and observing the reflected or transmitted gentle through a microscope. By examining the surface morphology and defects, the crystal high-quality could be identified.
Overall, the characterization solutions reviewed In this particular chapter supply beneficial insights into your solutions employed for the characterization of LBO nonlinear crystals.
Superior intensity, brief pulse lasers with shorter wavelengths have enabled quite a few production procedures, or enhanced the outcomes acquired from far more conventional lasers. Those features make achievable a much scaled-down, even negligible HAZ (heat influenced zone) about The situation of beam impingement.
The magnitude in the powerful nonlinear coefficient is dependent upon the nonlinear tensor parts and to the utilized stage-matching configuration. A higher nonlinearity is very important especially When the achievable optical intensities are reduced.
For buyer convenience and security of crystals, regular 1" anodized aluminum (Al) mounts is often offered upon request. The mounted crystals is often further mounted in a conventional 1" mirror mount to get angle tuned for section matching (
In sum, the distinctive combination of overall performance and toughness that LBO Crystals give set them apart on the earth of nonlinear optics.
