Within this paper, The brand new lapping slurry and sharpening slurry are launched. Along with the deliquescence degree of CLBO is fallen to most affordable. A different working know-how is additionally adopted. Soon after tough sprucing, the concentration of extremely-precision sprucing slurry is elevated effectively. So does the ultra-precision polishing speed, as well as the wiping speed is faster compared to the deliquescence pace. The CLBO crystal surface area roughness can attain 1nm and maintain the floor top quality effectively. Entry by means of your institution

In accordance with the proof-of-basic principle experiment, the conversion efficiency of 23% implied the potential for achieving higher-electricity at the next Stokes wavelength with the Raman laser. Should the pump laser of 1078 nm could be obtained at the typical power of 50 W, the output energy of its 2nd Stokes wavelength at 1512 nm could possibly be over 10 W. The look in the Raman laser cavity needs to be optimized in an effort to stay away from the problems with the M1 and diamond floor.
The normal energy on the NIR laser nevertheless has the opportunity to get improved to tens of watts including 70 W [26] Should the double-move configuration could possibly be used to the Yb:YAG SCF amplifier phase. That's why, if the conversion effectiveness of 31% from NIR to DUV might be however preserved at this greater electrical power ailment, the typical output electric power from the DUV laser at 258 nm may be more than 20 W, which would become a amazing electricity amount for the DUV laser and lead to the unanticipated DUV laser machining final results. Additionally, for prime-electric power DUV laser, the UV destruction of your nonlinear crystal, such as the Home windows for CLBO crystal along with the mirrors, is another crucial parameter for long-term and secure Procedure.

Due to the thermal lens influence within the good-condition lasers, Should the heating management is insufficient, It's not at all effortless to acquire the strong-point out laser that has a higher electrical power in addition to a superior beam good quality simultaneously. Not long ago, with the event of the thin disk laser and solitary-crystal fiber (SCF) laser, a significant-energy laser at the basic wavelength (one μm) were realized with an excellent beam high-quality even with a TEM00 manner beam [4,24], which would be great candidates for the basic on the DUV laser website era. A different prospect for the basic could be the substantial-electricity fiber laser which may very well be realized by coherent beam mix with M2 price below 1.
On the other facet, the facility scaling on the NIR laser is another element to enhance the normal electricity of your 193-nm DUV laser. Due to insufficient the higher-energy amplification Alternative on the NIR laser (for instance at 1553 nm), nonlinear frequency procedures like optical parameter oscillation (OPO) may very well be applied to make a wavelength converter by shifting the wavelength from one μm to the desired wavelength and also getting relative bigger electrical power [21]. Just lately, a diamond Raman laser showed its ability in attaining a substantial ability and also a superior conversion performance at the 1st Stokes from the 1-μm laser [22,23], which implies the possibility to be applied in the 193-nm DUV laser era as a consequence of its substantial Raman obtain and large frequency change.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics from the Nd:YAG fundamental laser wavelength. To be able to improve the damage threshold, very low CLBO surface area roughness, by extremely-precision machining, is needed. As the CLBO crystal has quick hydroscopic reaction and micro scratches in machining, extremely-precise machining of your CLBO crystal can be a difficult complex problem.

The conversion effectiveness from fundamental NIR to DUV is from five% to 36% in accordance with the noted leads to Table 1. Expanding the conversion efficiency will decrease the stress on the design and setup of the basic laser amplifier as well as the electrical ability consumption. An excellent beam high-quality of the fundamental laser will even lead towards the growing in the conversion effectiveness and also the suitable electricity depth on the NIR and eco-friendly laser inside the SHG and FHG approach, respectively. The best conversion efficiencies from NIR to environmentally friendly and environmentally friendly to DUV laser by utilization of CLBO crystal are 70% and close to 50%, respectively [twelve], which corresponds on the conversion effectiveness of 35% from fundamental to DUV.
