All-reliable-state ultraviolet lasers have been widely used in the fields of mechanical flaw detection, lithography, micromachining and drugs for some great benefits of small quantity, extensive life, high effectiveness, excellent beam high quality, wide tuning and slender spectral line, and so forth. Utilizing high ability in close proximity to-infrared coherent gentle source as the elemental frequency supply determined by nonlinear tuning know-how, creating ultraviolet coherent radiation by multistage frequency conversion is considered an essential way to acquire the ultraviolet coherent mild resource.
In comparison to BBO it options larger sized spectral and temperature acceptance, superior angle tolerance, as well as a scaled-down stroll-off angle. from 3289 $ delivery
According to the proof-of-basic principle experiment, the conversion performance of 23% implied the potential of acquiring substantial-energy at the second Stokes wavelength in the Raman laser. If your pump laser of 1078 nm can be attained at the standard ability of fifty W, the output electric power of its 2nd Stokes wavelength at 1512 nm may very well be in excess of 10 W. The look of your Raman laser cavity must be optimized in an effort to avoid the damage of your M1 and diamond floor.
As an example, The present concave OC could get replaced by a aircraft mirror which could mitigate the power density on the floor of M1 along with the diamond. In addition, applying large damage threshold coatings for M1 and diamond would also Enhance the output ability with no damages. Then, the NIR laser within the 2nd Stokes wavelength may very well be higher more than enough, along with its superior beam good quality, to deliver the final DUV laser at 193 nm that has a large ordinary energy.
Conversely, the beam top quality of the larger ability DUV laser would grow to be even worse due to a lot more really serious thermal and nonlinear consequences. Therefore, the frequency conversion processes need to be thoroughly meant to mitigate the aforementioned results. So, a higher-electricity DUV laser at the FHG of one μm with an excellent beam high quality could be attained and can be effective for obtaining the shorter wavelength DUV lasers such as 193 nm by SFG.
