The 2-Minute Rule for CLBO Crystal

With this paper, The brand new lapping slurry and sharpening slurry are launched. As well as the deliquescence diploma of CLBO is fallen to most affordable. A completely new Operating know-how is likewise adopted. Soon after rough sharpening, the focus of extremely-precision sharpening slurry is increased adequately. So does the ultra-precision polishing speed, plus the wiping velocity is quicker compared to the deliquescence speed. The CLBO crystal surface area roughness can accomplish 1nm and retain the surface area excellent perfectly. Obtain via your institution

When compared with BBO it options more substantial spectral and temperature acceptance, greater angle tolerance, and also a lesser wander-off angle. from 3289 $ shipping

In accordance with the evidence-of-principle experiment, the conversion effectiveness of 23% implied the possibility of attaining large-ability at the second Stokes wavelength on the Raman laser. If your pump laser of 1078 nm could possibly be attained at the common electric power of 50 W, the output electricity of its 2nd Stokes wavelength at 1512 nm could be in excess of 10 W. The look in the Raman laser cavity needs to be optimized in order to avoid the harm on the M1 and diamond area.

For example, The present concave OC could be replaced by a airplane mirror which could mitigate the ability density over the area of M1 along with the diamond. Furthermore, working with higher hurt threshold coatings for M1 and diamond would also Enhance the output electrical power with no damages. Then, the NIR laser in the 2nd Stokes wavelength could possibly be high more than enough, and also its great beam good quality, to deliver the final DUV laser at 193 nm by using a higher typical energy.

LBO can be an excellent nonlinear crystal which is usually applied to the SHG through the NIR on the environmentally friendly. The DUV laser will likely be recognized by two phases of SFG inside the LBO crystals due to the fact there's no period-matching angle for LBO to transform the environmentally friendly laser at 515 nm or 532 nm towards the DUV right by SHG [sixteen]. Recently, the NSBBF crystal has also shown its opportunity to obtain a large conversion effectiveness from 532 nm to 266 nm. The stroll-off angle and deff on the NSBBF are Just about just like People of CLBO [17].

From the scientific and industrial programs, the beam good quality on the DUV laser is also a significant parameter. Notably, the beam good quality with the DUV laser dramatically has an effect on the laser machining results. The beam high quality on the DUV laser is set by that of the fundamental laser as well as crystal with the frequency conversion. A short while ago, a superior-electrical power DUV laser (>10 W) at 258 nm was described that has a beam top quality of M2 < one.5, which was created by FHG of a Yb:YAG laser at 1030 nm utilizing the CLBO crystal [thirteen]. This laser would lead to an even better laser machining consequence as compared to the earlier DUV lasers with more substantial M2.

The beam profile click here demonstrated in Figure 7b demonstrated a good beam high-quality as one of many deserves of Raman laser, which might be advantageous to make a 193-nm DUV laser with a top quality beam.

Its UV absorption edge reaches 180 nm. The powerful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as massive as that of KDP. CLBO crystals is usually developed from the stoichiometric soften with lessen viscosity.
