All-strong-condition ultraviolet lasers are greatly Employed in the fields of mechanical flaw detection, lithography, micromachining and medication for the benefits of tiny volume, lengthy lifestyle, higher effectiveness, great beam high quality, wide tuning and slim spectral line, and so forth. Utilizing superior electricity in the vicinity of-infrared coherent gentle source as the basic frequency source dependant on nonlinear tuning know-how, producing ultraviolet coherent radiation by multistage frequency conversion is considered to be a vital way to create the ultraviolet coherent light-weight source.
Compared to BBO it attributes much larger spectral and temperature acceptance, better angle tolerance, plus a lesser wander-off angle. from 3289 $ delivery
According to the proof-of-theory experiment, the conversion effectiveness of 23% implied the opportunity of reaching superior-electrical power at the next Stokes wavelength on the Raman laser. If your pump laser of 1078 nm can be attained at the standard ability of 50 W, the output electrical power of its 2nd Stokes wavelength at 1512 nm could possibly be more than 10 W. The look with the Raman laser cavity really should be optimized so as to stay away from the harm of your M1 and diamond surface area.
The typical electrical power from the NIR laser still has the opportunity being improved to tens of watts which include 70 W [26] In case the double-pass configuration may very well be utilized with the Yb:YAG SCF amplifier stage. Hence, If your conversion efficiency of 31% from NIR to DUV may very well be nonetheless preserved at this higher electrical power ailment, the typical output electric power of your DUV laser at 258 nm could possibly be much more than twenty W, which would be considered a impressive ability amount for the DUV laser and lead to the unanticipated DUV laser machining success. Moreover, for high-energy DUV laser, the UV harm in the nonlinear crystal, including the Home windows for CLBO crystal as well as mirrors, is yet another significant parameter for lasting and steady operation.

LBO is likewise a great nonlinear crystal which is usually placed on the SHG in the NIR on the green. The DUV laser is often understood by two levels of SFG in the LBO crystals considering that there is no phase-matching angle for LBO to convert the green laser at 515 nm or 532 nm to the DUV right by SHG [16]. Just lately, the NSBBF crystal has also proven its prospective to get a large conversion efficiency from 532 nm to 266 nm. The walk-off angle and deff of your NSBBF are almost comparable to All those of CLBO [17].

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the most effective non-linear crystal which generates ultraviolet harmonics in the Nd:YAG basic laser wavelength. To be able to enhance the destruction threshold, lower CLBO surface roughness, by extremely-precision machining, is needed. Since the CLBO crystal has simple hydroscopic response and micro scratches in machining, extremely-precise machining with the CLBO crystal is really a complicated complex issue.
