The level of the solvent is usually altered for various crystal dimensions Hence the lens tissue is stored moist for the entire drag but there's not any noticeable trace of solvent about the crystal surface after the drag is finished. Inspect the floor and repeat if important, but only use Each and every sheet of lens tissue as soon as.
Hi there, thanks for getting in contact with Thorlabs. The wavelength ranges on the antireflective coatings on these β-BBO crystals align Along with the respective wavelength bands that these crystals are optimized for. Requests for customizations is usually produced by reaching out to us at techsupport@thorlabs.com
The destruction Evaluation are going to be completed on an analogous optic (customer's optic will not be destroyed). Tests may well bring about additional prices or guide occasions. Contact Tech Assist For more info.
Certainly, BBO crystals could be customized to fulfill unique requirements. This incorporates tailor made sizes, designs, and coatings. Custom made dimensions and designs is usually cut to suit distinct optical programs, though tailor made coatings is often applied to greatly enhance the crystal’s overall performance in specified programs.
Hygroscopic crystal products deteriorate when they are not often saved in sufficiently dry air (or simply a dry purge gas). This applies e.g. to KDP and BBO, and in a lesser extent to LBO. It may be handy to help keep this type of crystal at a somewhat elevated temperature, which makes it easier to keep it dry.
). This spatial concentrating constraint within the SHG course of action will normally lead to the crystal duration constantly getting below the Rayleigh choice of the input focused pulse.
There's two velocities that determine the propagation of light in optical media: the stage and team velocities. The period velocity could be the velocity of your copyright, the oscillation of the electrical field, as well as the velocity that's matched among the basic and 2nd harmonic frequencies for stage matching. The stage velocity relative towards the velocity of light inside a vacuum is defined through the index of refraction.
When pulse lengths are among one ns and one µs, laser-induced damage can occur either on account of absorption or a dielectric breakdown (consequently, a user should Examine both of those CW and pulsed LIDT). Absorption is possibly due to an intrinsic residence in the optic or resulting from floor irregularities; So LIDT values are only valid for optics meeting or exceeding the area high-quality requirements supplied by a manufacturer.
Higher-precision laser microfabrication is a technique the place materials are processed and modified over a microscopic scale. This process demands a laser supply that can deliver exceptionally targeted and specific beams of sunshine. The 266nm wavelength is particularly appropriate for this as a consequence of its limited wavelength, which makes sure that the laser beam may be concentrated to get more info an exceedingly compact place sizing.
A: The wide transparency array presents versatility, making it possible for BBO crystals to be used throughout a various number of wavelengths and applications.
Pumped with the fourth harmonic of a Nd:YAG laser (at 266nm), a tunable OPO with sign wavelength assortment among 422nm and 477nm continues to be noticed by angle-tuning a kind I BBO crystal. Pumped by a 1mJ, 80fs Dye laser at 615nm, the OPA with two BBO crystals yields a lot more than 50µJ (most a hundred thirtyµJ),
The crystal axis is c. The chief ray is parallel to the direction used to evaluate the tuning angle (θ), that's optimized during section matching. Conversion effectiveness is optimized for rays parallel to your Main ray and worse for rays at bigger angles (ψ) on the chief ray.
BBO crystals should be taken care of with care to avoid scratching or harmful their surfaces. They need to be saved in a very dry, great place and held away from direct daylight. Typical cleaning having a comfortable fabric or air blower is recommended to maintain their optical performance. When managing BBO crystals, it’s imperative that you use gloves to circumvent oils through the pores and skin from contaminating the crystal floor.
Eventually, the Slice crystals are polished into a smooth complete. This sharpening course of action not only improves the aesthetic physical appearance of the crystals but in addition improves their optical Attributes by lessening area imperfections.
