A Simple Key For CLBO Crystal Unveiled
Blog Article
All-sound-condition ultraviolet lasers are actually broadly used in the fields of mechanical flaw detection, lithography, micromachining and medicine for some great benefits of little volume, extended lifetime, significant performance, very good beam excellent, vast tuning and narrow spectral line, etc. Employing substantial electrical power near-infrared coherent light-weight resource as the fundamental frequency source depending on nonlinear tuning technological innovation, producing ultraviolet coherent radiation by multistage frequency conversion is regarded as a very important technique to build the ultraviolet coherent gentle source.
Compared to BBO it capabilities larger spectral and temperature acceptance, much better angle tolerance, plus a scaled-down stroll-off angle. from 3289 $ supply

For instance, the current concave OC could get replaced by a airplane mirror which could mitigate the ability density within the area of M1 as well as diamond. Additionally, employing large hurt threshold coatings for M1 and diamond would also Enhance the output electrical power with none damages. Then, the NIR laser with the 2nd Stokes wavelength can be higher ample, and its excellent beam excellent, to generate the final DUV laser at 193 nm using a higher ordinary electrical power.

On one other aspect, the ability scaling of your NIR laser is yet another part to improve the normal electric power on the get more info 193-nm DUV laser. A result of the deficiency of the higher-ability amplification Resolution from the NIR laser (such as at 1553 nm), nonlinear frequency processes for instance optical parameter oscillation (OPO) could possibly be applied to establish a wavelength converter by shifting the wavelength from 1 μm to the desired wavelength together with obtaining relative larger ability [21]. Recently, a diamond Raman laser confirmed its means in accomplishing a superior energy plus a substantial conversion efficiency in the 1st Stokes with the 1-μm laser [22,23], which implies the likelihood for being used inside the 193-nm DUV laser technology because of its substantial Raman acquire and enormous frequency change.

The beam profile demonstrated in Determine 7b shown a great beam good quality as on the list of merits of Raman laser, which would be beneficial to create a 193-nm DUV laser with a high quality beam.
