The 2-Minute Rule for CLBO Crystal

Blog Article

All-strong-condition ultraviolet lasers are commonly Employed in the fields of mechanical flaw detection, lithography, micromachining and medication for the benefits of tiny quantity, very long lifetime, higher efficiency, good beam top quality, extensive tuning and slender spectral line, etc. Using higher electric power in close proximity to-infrared coherent gentle supply as the elemental frequency supply dependant on nonlinear tuning technologies, generating ultraviolet coherent radiation by multistage frequency conversion is considered to be a crucial method to build the ultraviolet coherent mild supply.

In comparison with BBO it functions greater spectral and temperature acceptance, much better angle tolerance, as well as a more compact stroll-off angle. from 3289 $ delivery

The common ability of the NIR laser nonetheless has the possible to become improved to tens of watts which include 70 W [26] Should the double-move configuration might be used for your Yb:YAG SCF amplifier stage. Consequently, if the conversion effectiveness of 31% from NIR to DUV could be even now maintained at this increased power issue, the normal output power in the DUV laser at 258 nm can be a lot more than 20 W, which would certainly be a exceptional electrical power amount for the DUV laser and bring about the unanticipated DUV laser machining benefits. Additionally, for top-electric power DUV laser, the UV injury on the nonlinear crystal, including the windows for CLBO crystal and also the mirrors, is another important parameter for long-term and secure Procedure.

Both the 1040 nm and 1078 nm laser come from one dual-wavelength Yb-doped fiber laser. Every laser is amplified by stages of fiber amplifier and Yb-doped components amplifier, respectively.

While in the scientific and industrial apps, the beam excellent with the DUV laser can also be a vital parameter. Notably, the beam good quality of the DUV laser radically has an effect on the laser machining effects. The beam top quality in the DUV laser is decided by that of the elemental laser plus the crystal to the frequency conversion. Not too long ago, a high-ability DUV laser (>10 W) at 258 nm was reported which has a beam excellent of M2 < 1.5, which was created by FHG of a Yb:YAG laser at 1030 nm using the CLBO crystal [thirteen]. This laser would bring about an improved laser machining end result compared to the preceding DUV lasers with larger sized M2.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the most effective non-linear crystal which generates ultraviolet harmonics from the Nd:YAG basic laser wavelength. In an effort to CLBO Crystal enrich the problems threshold, very low CLBO floor roughness, by ultra-precision machining, is needed. As the CLBO crystal has quick hydroscopic response and micro scratches in machining, ultra-precise machining with the CLBO crystal can be a challenging technical challenge.
