A Review Of CLBO Crystal
Blog Article
All-good-point out ultraviolet lasers are actually extensively Utilized in the fields of mechanical flaw detection, lithography, micromachining and drugs for the advantages of tiny volume, prolonged everyday living, high efficiency, very good beam excellent, extensive tuning and narrow spectral line, etcetera. Making use of large energy near-infrared coherent gentle resource as the basic frequency resource based upon nonlinear tuning technology, producing ultraviolet coherent radiation by multistage frequency conversion is regarded as an important way to acquire the ultraviolet coherent mild supply.
When compared with BBO it attributes much larger spectral and temperature acceptance, better angle tolerance, plus a lesser wander-off angle. from 3289 $ delivery

The typical electric power with the NIR laser however has the probable being improved to tens of watts like 70 W [26] When the double-go configuration could possibly be used for your Yb:YAG SCF amplifier phase. That's why, If your conversion effectiveness of 31% from NIR to DUV may be even now maintained at this better energy problem, the common output electrical power of your DUV laser at 258 nm may be over 20 W, which would certainly be a exceptional electrical power degree to the DUV laser and cause the unanticipated DUV laser machining results. Also, for high-electricity DUV laser, the UV problems of your nonlinear crystal, such as the Home windows for CLBO crystal plus the mirrors, is an additional critical parameter website for long run and stable operation.

In the scientific and industrial purposes, the beam high-quality of your DUV laser is usually a very important parameter. Specially, the beam good quality in the DUV laser significantly affects the laser machining outcomes. The beam high-quality on the DUV laser is determined by that of the basic laser and also the crystal with the frequency conversion. Just lately, a superior-electricity DUV laser (>ten W) at 258 nm was noted using a beam quality of M2 < 1.five, which was created by FHG of a Yb:YAG laser at 1030 nm utilizing the CLBO crystal [thirteen]. This laser would produce an improved laser machining result when compared to the previous DUV lasers with more substantial M2.

Furthermore, combining the stable-state laser with other nonlinear course of action such as stimulated Raman scattering, NIR lasers may be obtained at new wavelengths with large electric power and substantial beam excellent, which was analyzed by the proof-of-principle experiment. This Raman laser plan provides a brand new route to the high-energy DUV laser, especially for the wavelength of 193 nm.
