All-solid-point out ultraviolet lasers have already been commonly Employed in the fields of mechanical flaw detection, lithography, micromachining and medication for the benefits of smaller quantity, very long everyday living, large efficiency, fantastic beam high-quality, extensive tuning and narrow spectral line, and many others. Utilizing superior electricity near-infrared coherent light supply as the basic frequency source based on nonlinear tuning engineering, building ultraviolet coherent radiation by multistage frequency conversion is considered a crucial solution to establish the ultraviolet coherent light-weight resource.

By way of example, the current concave OC could be replaced by a airplane mirror which could mitigate the facility density on the floor of M1 and the diamond. In addition, utilizing large hurt threshold coatings for M1 and diamond would also Enhance the output electricity with no damages. Then, the NIR laser with the 2nd Stokes wavelength can be high more than enough, and its superior beam high-quality, to deliver the ultimate DUV laser at 193 nm by using a substantial regular electrical power.
On the other hand, the beam good quality of this larger electrical power DUV laser would come to be even worse resulting from far more significant thermal and nonlinear results. Consequently, the frequency conversion procedures must be very carefully designed to mitigate the aforementioned effects. So, a large-electrical power DUV laser within the FHG of 1 μm with a superb beam top quality can be obtained and will be effective for getting the shorter wavelength DUV lasers like 193 nm by SFG.
LBO can also be an excellent nonlinear crystal which is often applied to the SHG within the NIR on the green. The DUV laser is frequently understood by two stages of SFG in the LBO crystals because there isn't any period-matching angle for LBO to transform the eco-friendly laser at 515 nm or 532 nm into the DUV straight by SHG [sixteen]. Lately, the NSBBF crystal has also revealed its possible to obtain a significant conversion performance from 532 nm to 266 nm. The wander-off angle and deff of the NSBBF are Virtually much like Individuals of CLBO [seventeen].
On another facet, the ability scaling of the NIR laser is yet another component to improve the common ability on the 193-nm DUV laser. Because of the deficiency of the large-ability amplification Resolution with the NIR laser (as an example at 1553 nm), nonlinear frequency processes for instance optical parameter oscillation (OPO) could possibly be applied to make a wavelength converter by shifting the wavelength from one μm to the specified wavelength together with obtaining relative higher energy [21]. Lately, a diamond Raman laser confirmed its capability in acquiring a large ability as well as a high conversion performance on the 1st Stokes in the 1-μm laser [22,23], which read more implies the possibility for being utilized in the 193-nm DUV laser era due to its high Raman gain and enormous frequency shift.

In addition, combining the good-state laser with other nonlinear system for instance stimulated Raman scattering, NIR lasers may very well be accomplished at new wavelengths with high electricity and high beam top quality, which was analyzed via the proof-of-basic principle experiment. This Raman laser scheme delivers a new path to the high-electric power DUV laser, Specifically within the wavelength of 193 nm.
