With this paper, The brand new lapping slurry and polishing slurry are introduced. And the deliquescence degree of CLBO is fallen to cheapest. A new Performing technologies can be adopted. Just after tough sprucing, the focus of extremely-precision sharpening slurry is amplified properly. So does the extremely-precision sprucing velocity, as well as wiping velocity is quicker compared to deliquescence speed. The CLBO crystal surface roughness can obtain 1nm and hold the surface area high quality nicely. Obtain by your institution

Both the 1040 nm and 1078 nm laser come from one dual-wavelength Yb-doped fiber laser. Each laser is amplified by phases of fiber amplifier and Yb-doped supplies amplifier, respectively.
On the opposite aspect, the ability scaling on the NIR laser is an additional element to increase the normal electricity in the 193-nm DUV laser. Because of the deficiency of the read more large-electricity amplification Answer with the NIR laser (as an example at 1553 nm), nonlinear frequency processes like optical parameter oscillation (OPO) could be placed on make a wavelength converter by shifting the wavelength from one μm to the desired wavelength and also getting relative higher electricity [21]. A short while ago, a diamond Raman laser showed its ability in attaining a substantial electric power and a high conversion efficiency on the 1st Stokes on the 1-μm laser [22,23], which suggests the likelihood for being applied inside the 193-nm DUV laser generation due to its substantial Raman achieve and huge frequency shift.

In the scientific and industrial applications, the beam quality of the DUV laser is also a very important parameter. Significantly, the beam excellent on the DUV laser drastically affects the laser machining success. The beam top quality from the DUV laser is decided by that of the fundamental laser as well as crystal to the frequency conversion. Lately, a large-power DUV laser (>10 W) at 258 nm was described having a beam excellent of M2 < one.5, which was generated by FHG of a Yb:YAG laser at 1030 nm utilizing the CLBO crystal [thirteen]. This laser would bring about an improved laser machining final result in comparison with the preceding DUV lasers with larger sized M2.

The development from the 193-nm laser was shown by levels of SFG. In an effort to scale the DUV laser power properly, a new notion with the 193-nm DUV laser technology is presented determined by the diamond Raman laser.
