5 Easy Facts About CLBO Crystal Described

With this paper, The brand new lapping slurry and polishing slurry are introduced. Along with the deliquescence diploma of CLBO is fallen to most affordable. A whole new working engineering is likewise adopted. Just after tough sprucing, the focus of extremely-precision sharpening slurry is greater thoroughly. So does the ultra-precision polishing velocity, as well as wiping velocity is quicker in comparison to the deliquescence pace. The CLBO crystal surface area roughness can attain 1nm and maintain the surface high quality well. Obtain by your institution
As compared to BBO it functions much larger spectral and temperature acceptance, better angle tolerance, as well as a lesser wander-off angle. from 3289 $ delivery
According to the proof-of-principle experiment, the conversion efficiency of 23% implied the potential of obtaining superior-power at the 2nd Stokes wavelength of the Raman laser. When the pump laser of 1078 nm may be received at the normal electric power of 50 W, the output electrical power of its 2nd Stokes wavelength at 1512 nm could possibly be over 10 W. The design on the Raman laser cavity should be optimized as a way to steer clear of the injury on the M1 and diamond surface.
By way of example, The present concave OC could be replaced by a airplane mirror which could mitigate the ability density within the surface of M1 as well as diamond. Furthermore, using significant injury threshold coatings for M1 and diamond would also Increase the output electricity without any damages. Then, the NIR laser with the 2nd Stokes wavelength could possibly be superior ample, as well as its excellent beam high-quality, to deliver the final DUV laser at 193 nm that has a high typical electric power.

LBO can also be a wonderful nonlinear crystal which is always placed on the SHG from the NIR into the inexperienced. The DUV laser will likely be realized by two phases of SFG within the LBO crystals since there is absolutely no stage-matching angle for LBO to transform the environmentally friendly laser at 515 nm or 532 nm to your DUV directly by SHG [16]. Not too long ago, the NSBBF crystal has also revealed its possible to acquire a significant conversion efficiency from 532 nm to 266 nm. The wander-off angle and deff on the NSBBF are Nearly comparable to People of CLBO [17].

Within the scientific and industrial applications, the beam quality of the DUV laser is also an important parameter. Particularly, the beam high-quality with the DUV laser substantially impacts the laser machining results. The beam excellent in the DUV laser is determined by that of the basic laser and also the crystal with the frequency conversion. Lately, a superior-electricity DUV laser (>ten W) at 258 nm was noted that has a beam high quality of M2 < 1.five, which was created here by FHG of a Yb:YAG laser at 1030 nm using the CLBO crystal [13]. This laser would produce a much better laser machining consequence in comparison to the preceding DUV lasers with larger sized M2.
