The Definitive Guide to CLBO Crystal

All-strong-point out ultraviolet lasers are actually widely used in the fields of mechanical flaw detection, lithography, micromachining and medication for the benefits of smaller quantity, very long life, substantial performance, very good beam good quality, vast tuning and narrow spectral line, etcetera. Making use of large energy near-infrared coherent gentle supply as the fundamental frequency source based on nonlinear tuning engineering, generating ultraviolet coherent radiation by multistage frequency conversion is regarded as a significant strategy to create the ultraviolet coherent light-weight source.

We summarized The present advancement status of the substantial-energy DUV laser both of those with the wavelength of FHG from the one-μm laser and at 193 nm. The recent progress from the good-state/fiber laser, together with the nonlinear optical crystals, prompts not just the normal power but additionally the beam high-quality (coherence) in the DUV lasers to an unparalleled amount.
The normal electricity in the NIR laser nonetheless has the opportunity to get enhanced to tens of watts which include 70 W [26] If your double-move configuration could possibly be used for that Yb:YAG SCF amplifier stage. Therefore, Should the conversion effectiveness of 31% from NIR to DUV could be continue to taken care of at this bigger electrical power ailment, the typical output electric power from the DUV laser at 258 nm may very well be more than 20 W, which would become a amazing electric power level to the DUV laser and bring on the unanticipated DUV laser machining results. In addition, for high-electric power DUV laser, the UV damage from the nonlinear crystal, including click here the windows for CLBO crystal as well as the mirrors, is another crucial parameter for long-term and stable Procedure.

A result of the thermal lens result within the solid-condition lasers, In the event the heating administration is insufficient, it is not uncomplicated to obtain the good-point out laser using a significant electric power as well as a high beam excellent simultaneously. A short while ago, with the development of The skinny disk laser and single-crystal fiber (SCF) laser, a substantial-power laser at the basic wavelength (1 μm) had been recognized with a very good beam top quality Despite having a TEM00 manner beam [four,24], which might be great candidates for the fundamental on the DUV laser era. A different applicant for the basic could be the superior-energy fiber laser which could be reached by coherent beam blend with M2 benefit less than one.
