Examine This Report on CLBO Crystal

Within this paper, the new lapping slurry and sprucing slurry are launched. As well as the deliquescence degree of CLBO is fallen to lowest. A whole new Doing the job technological innovation can be adopted. Just after tough sharpening, the focus of extremely-precision polishing slurry is elevated properly. So does the ultra-precision polishing velocity, and the wiping speed is faster compared to deliquescence pace. The CLBO crystal area roughness can obtain 1nm and maintain the surface area good quality nicely. Entry via your establishment

We summarized The present progress standing on the substantial-electricity DUV laser both at the wavelength of FHG of the 1-μm laser and at 193 nm. The latest growth on the stable-condition/fiber laser, as well as the nonlinear optical crystals, prompts not merely the standard ability but will also the beam top quality (coherence) from the DUV lasers to an unprecedented stage.

The crucial element difficulty of ultraviolet coherent mild supply largely focuses on the development of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal has become the ailments for frequency transformation, so the growth, dimensions, damage resistance, conversion performance and allowable parameter number of nonlinear optical crystal are needed A lot more.

Because of the thermal lens outcome inside the solid-condition lasers, if the heating management is insufficient, It's not at all easy to get the stable-state laser with a higher electrical power plus a significant beam quality concurrently. Not too long ago, with the development of the thin disk laser and single-crystal fiber (SCF) laser, a substantial-energy laser at the elemental wavelength (1 μm) had been recognized with a fantastic beam excellent In spite of a TEM00 mode beam [4,24], which might be superior candidates for the elemental in the DUV laser technology. A further applicant for the elemental could be the higher-ability fiber laser which might be realized by coherent beam mix with M2 worth fewer than one.

The pulse period of the next Stokes light was shortened to five ns as proven in Determine 7a, one-shot image from the oscilloscope, and that is a common phenomenon in Raman laser [forty four] though the heartbeat duration of the pump laser was ten ns.

Furthermore, combining the reliable-point out laser with other nonlinear approach like stimulated Raman scattering, NIR lasers can be attained at new wavelengths with superior electrical power and superior beam top quality, which was analyzed from the proof-of-theory experiment. This Raman laser plan offers a brand new path to the high-ability DUV laser, especially in the wavelength of 193 nm.

The conversion efficiency from basic NIR to DUV is from five% to 36% in accordance with the noted brings about Table one. Growing the conversion performance will decrease the load on the look and setup of the elemental laser amplifier in addition to the electrical electric power intake. A very good beam high-quality of the elemental laser will even contribute into the growing from the conversion performance and the suitable power depth on the NIR and environmentally friendly laser while in the SHG and FHG procedure, respectively. The best conversion efficiencies from NIR to environmentally friendly and eco-friendly to DUV laser by utilization of CLBO crystal are 70% and around fifty%, respectively [twelve], which corresponds to your conversion performance of 35% from fundamental to DUV.
