In this paper, the new lapping slurry and sprucing slurry are launched. Plus the deliquescence diploma of CLBO is fallen to cheapest. A brand new Doing the job technological innovation can also be adopted. Immediately after rough polishing, the focus of extremely-precision sprucing slurry is enhanced properly. So does the ultra-precision sharpening speed, as well as the wiping speed is quicker than the deliquescence velocity. The CLBO crystal area roughness can reach 1nm and maintain the surface excellent very well. Accessibility via your establishment

We summarized The present improvement status from the high-electric power DUV laser the two at the wavelength of FHG on the 1-μm laser and at 193 nm. The modern improvement with the strong-condition/fiber laser, as well as the nonlinear optical crystals, prompts not simply the average electricity but will also the beam top quality (coherence) on the DUV lasers to an unprecedented stage.
全固态紫外激光器以其体积小、寿命长、效率高、光束质量好、调谐范围宽、谱线窄等优点，广泛应用于机械探伤、光刻、微加工和医学等领域，等，利用大功率近红外相干光源作为基于非线性调谐技术的基频源，通过多级变频产生紫外相干辐射被认为是发展紫外相干光源的重要途径。紫外相干光源的关键问题是研制紫外波段的非线性光学变频晶体。非线性光学晶体是实现频率变换的条件之一，因此对非线性光学晶体的生长、尺寸、损伤电阻、转换效率和允许的参数范围提出了越来越高的要求。

The two the 1040 nm and 1078 nm laser come from one twin-wavelength Yb-doped fiber laser. Every single laser is amplified by stages of fiber amplifier and Yb-doped materials amplifier, respectively.
On another side, the ability scaling in the NIR laser is yet another element to enhance the ordinary electric power of the 193-nm DUV laser. Due to lack of the large-ability amplification Answer on the NIR laser (for example at 1553 nm), nonlinear frequency processes which include optical parameter oscillation (OPO) may very well be placed on create a wavelength converter by shifting the wavelength from one μm to the specified wavelength together with getting relative better ability [21]. Recently, a diamond Raman laser showed its means in achieving a high power and a high conversion efficiency for the 1st Stokes with the 1-μm laser [22,23], which implies the chance being utilized in the 193-nm DUV laser technology on account of its higher Raman attain and huge frequency change.

The heartbeat period of the second Stokes light was shortened to 5 ns as demonstrated in Determine 7a, just one-shot photo from the oscilloscope, which can be a standard phenomenon in Raman laser [44] although the heartbeat period of your pump laser was 10 ns.
In addition, combining the stable-point out laser with other nonlinear course of action including stimulated Raman scattering, NIR lasers may very well be obtained at new wavelengths with high power and higher beam high quality, which was tested by the evidence-of-basic principle experiment. This Raman laser scheme gives a fresh route to the high-power DUV laser, Primarily within the wavelength of 193 nm.
Tunable ultraviolet laser resource dependant on stable-condition dye laser engineering and CsLiB6O10 harmonic generation
Its UV absorption edge reaches a hundred and eighty nm. The successful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as massive as that of KDP. CLBO crystals can be grown from the stoichiometric melt with lessen viscosity.
