New Step by Step Map For CLBO Crystal

During this paper, the new lapping slurry and sharpening slurry are introduced. Plus the deliquescence diploma of CLBO is fallen to most affordable. A new Operating technological innovation is usually adopted. Following rough sprucing, the focus of extremely-precision sharpening slurry is amplified properly. So does the extremely-precision polishing speed, along with the wiping pace is quicker in comparison to the deliquescence velocity. The CLBO crystal area roughness can attain 1nm and preserve the surface area high quality well. Obtain by your institution

In accordance with the proof-of-principle experiment, the conversion effectiveness of 23% implied the potential for reaching significant-electric power at the second Stokes wavelength on the Raman laser. Should the pump laser of 1078 nm might be obtained at the typical electrical power of 50 W, the output power of its 2nd Stokes wavelength at 1512 nm might be over ten W. The design of the Raman laser cavity need to be optimized so as to stay away from the problems in the M1 and diamond surface area.

The common electrical power from the NIR laser continue to has the likely to get enhanced to tens of watts which include 70 W [26] Should the double-move configuration may be utilized for the Yb:YAG SCF amplifier phase. Consequently, Should the conversion effectiveness of 31% from NIR to DUV can be nevertheless managed at this larger ability problem, the typical output electric power on the DUV laser at 258 nm can be greater than 20 W, which would be considered a outstanding electric power level for your DUV laser and bring on the unanticipated DUV laser machining final results. Also, for top-electric power DUV laser, the UV destruction of your nonlinear crystal, such as the windows for CLBO crystal and also the mirrors, is another essential parameter for long-term and stable Procedure.

On the other facet, the ability scaling of the NIR laser is yet another factor to raise the ordinary power with the 193-nm DUV laser. Due to deficiency of the significant-electricity amplification Remedy of the NIR laser (such as at 1553 nm), nonlinear frequency processes such as optical parameter oscillation (OPO) can be applied to establish a wavelength converter by shifting the wavelength from 1 μm to the specified wavelength together with acquiring relative increased electrical power [21]. Lately, a diamond Raman click here laser showed its skill in achieving a large electricity in addition to a high conversion efficiency in the 1st Stokes in the 1-μm laser [22,23], which means the possibility for being applied inside the 193-nm DUV laser generation because of its higher Raman obtain and large frequency shift.

Its UV absorption edge reaches 180 nm. The effective nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as massive as that of KDP. CLBO crystals could be developed through the stoichiometric melt with lessen viscosity.
