All-reliable-condition ultraviolet lasers are greatly Employed in the fields of mechanical flaw detection, lithography, micromachining and medication for the benefits of modest quantity, very long lifetime, superior performance, excellent beam top quality, broad tuning and slender spectral line, and many others. Using higher power close to-infrared coherent light supply as the fundamental frequency supply depending on nonlinear tuning engineering, generating ultraviolet coherent radiation by multistage frequency conversion is viewed as a very important method to establish the ultraviolet coherent light-weight resource.

According to the proof-of-principle experiment, the conversion efficiency of 23% implied the possibility of attaining superior-power at the second Stokes wavelength in the Raman laser. In case the pump laser of 1078 nm can be attained at the average power of fifty W, the output electric power of its 2nd Stokes wavelength at 1512 nm can be much more than ten W. The look in the Raman laser cavity needs to be optimized to be able to avoid the problems on the M1 and diamond surface.
For example, The present concave OC could be replaced by a aircraft mirror which could mitigate the power density around the floor of M1 and also the diamond. Also, utilizing substantial damage threshold coatings for M1 and diamond would also improve the output electricity with none damages. Then, the NIR laser at the 2nd Stokes wavelength may be superior sufficient, and also its fantastic beam quality, to produce the final DUV laser at 193 nm having a higher common electrical power.

LBO can also be an outstanding nonlinear crystal which is often applied to the SHG from your NIR to your green. The DUV laser is often understood by two levels of SFG during the LBO crystals because there is not any section-matching angle for LBO to transform the environmentally friendly laser at 515 nm or 532 nm into the DUV instantly by SHG [sixteen]. A short while ago, the NSBBF crystal has also revealed its prospective to get a substantial conversion efficiency from 532 nm to 266 nm. The walk-off angle and deff of your NSBBF are Pretty much similar to those of CLBO [seventeen].
