In this paper, the new lapping slurry and sharpening slurry are released. As well as deliquescence degree of CLBO is fallen to cheapest. A different Doing the job technologies is also adopted. Immediately after rough sharpening, the focus of ultra-precision sharpening slurry is greater effectively. So does the ultra-precision polishing speed, and also the wiping speed is quicker than the deliquescence velocity. The CLBO crystal floor roughness can realize 1nm and retain the area high-quality well. Obtain as a result of your establishment

According to the proof-of-theory experiment, the conversion effectiveness of 23% implied the opportunity of achieving large-electric power at the second Stokes wavelength in the Raman laser. If your pump laser of 1078 nm could be acquired at the common ability of fifty W, the output power of its 2nd Stokes wavelength at 1512 nm might be greater than 10 W. The design in the Raman laser cavity needs to be optimized as a way to avoid the problems on the M1 and diamond surface area.
The key issue of ultraviolet coherent mild supply mostly focuses on the development of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is without doubt one of the situations for frequency transformation, so the growth, dimension, hurt resistance, conversion effectiveness and allowable parameter number of nonlinear optical crystal are required An increasing number of.
On the flip side, the beam high quality of the larger electric power DUV laser would turn out to be even worse as a consequence of a lot more really serious thermal and nonlinear consequences. That's why, the frequency conversion procedures should be very carefully built to mitigate the aforementioned consequences. So, a substantial-electrical power DUV laser for the FHG of one μm with a good beam high quality may be received and may be beneficial for obtaining the shorter wavelength DUV lasers like 193 nm by SFG.
The two the 1040 nm and 1078 nm laser come from one dual-wavelength Yb-doped fiber laser. Every laser is amplified by levels of fiber amplifier and Yb-doped products amplifier, respectively.

The beam profile shown in Figure 7b demonstrated a great beam top quality as one of several deserves of Raman laser, which would be effective to crank out a 193-nm DUV laser with a high quality beam.
