The 2-Minute Rule for CLBO Crystal

On this paper, the new lapping slurry and sprucing slurry are introduced. As well as the deliquescence diploma of CLBO is fallen to least expensive. A completely new Doing work technology can be adopted. Immediately after rough polishing, the concentration of ultra-precision sharpening slurry is enhanced effectively. So does the ultra-precision polishing pace, along with the wiping pace is quicker when compared to the deliquescence velocity. The CLBO crystal surface area roughness can accomplish 1nm and keep the surface area quality effectively. Accessibility as a result of your institution

When compared with BBO it capabilities greater spectral and temperature acceptance, much better angle tolerance, in addition to a smaller stroll-off angle. from 3289 $ supply

We summarized The existing progress status with the substantial-energy DUV laser both equally for the wavelength of FHG of your 1-μm laser and at 193 nm. The modern improvement of your strong-condition/fiber laser, in addition to the nonlinear optical crystals, prompts not only the average energy but additionally the beam high quality (coherence) with the DUV lasers to an unprecedented degree.

As an example, The existing concave OC could get replaced by a aircraft mirror which could mitigate the facility density about the surface area of M1 and also the diamond. Additionally, employing large injury threshold coatings for M1 and diamond would also improve the output electric power without any damages. Then, the NIR laser in the 2nd Stokes wavelength could possibly be superior sufficient, along with its great beam high quality, to make the final DUV laser at 193 nm by using a large typical energy.

On one other facet, the ability scaling with the NIR laser is an additional part to increase the regular power in the 193-nm DUV laser. Due to the insufficient the large-ability amplification solution from the NIR laser (such as at 1553 nm), nonlinear frequency processes such as optical parameter oscillation (OPO) may be applied to establish a wavelength converter by shifting the wavelength from one μm to the desired wavelength and also obtaining relative increased ability [21]. Not long ago, a diamond Raman laser confirmed its potential in accomplishing a higher ability as well as a superior conversion effectiveness at the 1st Stokes of the 1-μm laser [22,23], which implies the chance to generally be utilized while in the 193-nm DUV laser era because of its large Raman get and huge frequency shift.

Inside the scientific and industrial purposes, the beam excellent with the DUV laser can also be a significant parameter. Especially, the beam good quality of your DUV laser dramatically affects the laser machining results. The beam good quality of your DUV laser is decided by that of the elemental laser as well as the crystal for that frequency conversion. A short while ago, a higher-energy DUV laser (>10 W) at 258 nm was noted using a beam good quality of M2 < 1.five, which was generated by FHG of a Yb:YAG laser read more at 1030 nm using the CLBO crystal [thirteen]. This laser would produce a much better laser machining outcome compared to the previous DUV lasers with much larger M2.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the most effective non-linear crystal which generates ultraviolet harmonics of your Nd:YAG elementary laser wavelength. So that you can boost the harm threshold, reduced CLBO area roughness, by extremely-precision machining, is required. As the CLBO crystal has effortless hydroscopic response and micro scratches in machining, ultra-precise machining from the CLBO crystal is a tricky specialized problem.
