All-stable-point out ultraviolet lasers have already been widely Employed in the fields of mechanical flaw detection, lithography, micromachining and medicine for the advantages of smaller quantity, extended everyday living, higher efficiency, good beam high quality, wide tuning and slender spectral line, and so forth. Utilizing high ability in close proximity to-infrared coherent mild source as the basic frequency source according to nonlinear tuning technological innovation, creating ultraviolet coherent radiation by multistage frequency conversion is thought to be an important solution to produce the ultraviolet coherent light resource.
When compared with BBO it characteristics much larger spectral and temperature acceptance, better angle tolerance, and also a more compact stroll-off angle. from 3289 $ delivery
We summarized The present enhancement standing in the high-electric power DUV laser equally in the wavelength of FHG with the 1-μm laser and at 193 nm. The the latest growth with the sound-point out/fiber laser, plus the nonlinear optical crystals, prompts not only the common power and also the beam high quality (coherence) with the DUV lasers to an unprecedented amount.
The standard ability with the NIR laser nevertheless has the prospective for being improved to tens of watts such as 70 W [26] When the double-go configuration might be utilized for your Yb:YAG SCF amplifier stage. As a result, if the conversion efficiency of 31% from NIR to DUV might be nonetheless maintained at this greater electric power affliction, the average output electric power with the DUV laser at 258 nm can be in excess of twenty W, which might be described as a remarkable power level with the DUV laser and produce the unanticipated DUV laser machining success. In addition, for top-power DUV laser, the UV damage of the nonlinear crystal, such as the Home windows for CLBO crystal and the mirrors, is yet another important parameter for lasting and stable Procedure.

LBO is usually an excellent nonlinear crystal which is usually applied to the SHG from your NIR for the eco-friendly. The DUV laser is often recognized by two stages of SFG from the LBO crystals considering that there isn't a period-matching angle for LBO to transform the inexperienced laser at 515 nm or 532 nm to your DUV specifically by SHG [sixteen]. Not long ago, the NSBBF crystal has also demonstrated its prospective to obtain a superior conversion effectiveness from 532 nm to 266 nm. The wander-off angle and deff on the NSBBF are almost comparable to These of CLBO [seventeen].

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics on the Nd:YAG elementary laser wavelength. So as to enrich the problems threshold, very low CLBO floor roughness, by ultra-precision machining, is needed. As the CLBO crystal has uncomplicated hydroscopic reaction and micro scratches in machining, ultra-specific machining with the CLBO crystal is actually a hard specialized trouble.
Tunable ultraviolet laser resource dependant on stable-state dye laser technology and CsLiB6O10 harmonic technology
