5 Easy Facts About CLBO Crystal Described
Blog Article
All-stable-point out ultraviolet lasers happen to be broadly Utilized in the fields of mechanical flaw detection, lithography, micromachining and drugs for some great benefits of tiny volume, lengthy lifestyle, substantial efficiency, great beam quality, wide tuning and slender spectral line, and so on. Employing higher energy near-infrared coherent light-weight supply as the fundamental frequency resource dependant on nonlinear tuning technological know-how, generating ultraviolet coherent radiation by multistage frequency conversion is viewed as a crucial solution to build the ultraviolet coherent light-weight source.
When compared to BBO it attributes more substantial spectral and temperature acceptance, much better angle tolerance, and a lesser walk-off angle. from 3289 $ shipping and delivery
We summarized the current progress standing from the high-electrical power DUV laser both for the wavelength of FHG of your one-μm laser and at 193 nm. The latest development of your reliable-condition/fiber laser, in addition to the nonlinear optical crystals, prompts not only the standard energy and also the beam quality (coherence) in the DUV lasers to an unparalleled amount.
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 the diamond. In addition, using significant destruction threshold coatings for M1 and diamond would also Enhance the output electricity with none damages. Then, the NIR laser within the 2nd Stokes wavelength might be superior ample, and its great beam good quality, to crank out the ultimate DUV laser at 193 nm which has a superior normal electric power.

Inside the scientific and industrial programs, the beam quality of the DUV laser can also be a crucial parameter. Specifically, the beam top quality in the DUV laser drastically affects the laser machining results. The beam high-quality with the DUV laser is decided by that of the fundamental laser along with the crystal for your frequency conversion. Lately, a superior-electric power DUV laser (>10 W) at 258 nm was documented with a beam good quality of M2 < one.5, which was generated by FHG of a Yb:YAG laser at 1030 nm using the CLBO crystal [13]. This laser would produce a much better laser machining consequence in comparison to the earlier DUV lasers with larger sized M2.
You may also Verify the achievable obtain by using own account by logging in or/and check accessibility by means of your establishment.
Moreover, combining the reliable-point out laser with other nonlinear course of action for example stimulated Raman scattering, NIR lasers might be realized at new wavelengths with high electricity and high beam top quality, which was examined via the proof-of-principle experiment. This Raman laser scheme delivers a new route to the large-energy DUV laser, Specially for the wavelength of 193 nm.

Its UV absorption edge reaches a hundred and eighty nm. The productive nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about twice as significant as that of KDP. CLBO crystals could be developed from your stoichiometric soften with reduced viscosity.
