During this paper, the new lapping slurry and sprucing slurry are introduced. Plus the deliquescence degree of CLBO is fallen to most affordable. A completely new working engineering can also be adopted. Just after tough sprucing, the focus of extremely-precision sharpening slurry is increased effectively. So does the extremely-precision sprucing speed, along with the wiping velocity is quicker than the deliquescence speed. The CLBO crystal surface roughness can achieve 1nm and keep the area quality effectively. Access through your institution

In accordance with the evidence-of-principle experiment, the conversion effectiveness of 23% implied the possibility of accomplishing high-electricity at the 2nd Stokes wavelength of your Raman laser. If the pump laser of 1078 nm could possibly be acquired at the common electricity of 50 W, the output energy of its 2nd Stokes wavelength at 1512 nm might be over 10 W. The look with the Raman laser cavity really should be optimized so as to steer clear of the destruction in the M1 and diamond surface area.
The standard electric power on the NIR laser continue to has the probable for being improved to tens of watts like 70 W [26] if the double-go configuration could be used for your Yb:YAG SCF amplifier phase. For this reason, In case the conversion efficiency of 31% from NIR to DUV could be however maintained at this bigger electrical power ailment, the typical output electricity of the DUV laser at 258 nm could possibly be in excess of twenty W, which might be considered a amazing power degree for that DUV laser and bring about the unanticipated DUV laser machining success. What's more, for high-power DUV laser, the UV harm on the nonlinear crystal, including the Home windows for CLBO crystal and the mirrors, is an additional critical parameter for long-lasting and steady operation.

LBO can also be an outstanding nonlinear crystal which is always applied to the SHG through the NIR into the green. The DUV laser is normally recognized by two phases of SFG in the LBO crystals given that there is no stage-matching angle for LBO to convert the eco-friendly laser at 515 nm or 532 nm on the DUV right by SHG [sixteen]. A short while ago, the NSBBF crystal has also demonstrated its possible to obtain a large conversion effectiveness from 532 nm to 266 nm. The walk-off angle and deff in the NSBBF are Practically similar to those of CLBO [seventeen].

Additionally, combining the solid-condition laser with other nonlinear system for example stimulated Raman scattering, NIR lasers could be achieved at new wavelengths with substantial ability and substantial beam good quality, which was examined via the proof-of-principle experiment. This Raman laser scheme offers a fresh route to the large-electricity DUV laser, Specially with the wavelength of 193 nm.

The event of the 193-nm laser was demonstrated by phases of SFG. In an effort to scale the DUV laser energy proficiently, a completely new idea on the 193-nm DUV laser era is offered dependant on the diamond Raman laser.
