All-solid-state ultraviolet lasers happen to be greatly Employed in the fields of mechanical flaw detection, lithography, micromachining and drugs for the benefits of compact quantity, extended everyday living, high efficiency, great beam top quality, broad tuning and narrow spectral line, and many others. Utilizing higher power in the vicinity of-infrared coherent gentle source as the basic frequency resource based upon nonlinear tuning technological know-how, creating ultraviolet coherent radiation by multistage frequency conversion is viewed as a crucial solution to produce the ultraviolet coherent light supply.

The average energy from the NIR laser nonetheless has the possible to be enhanced to tens of watts for instance 70 W [26] In case the double-pass configuration could be used for the Yb:YAG SCF amplifier phase. Consequently, if the conversion effectiveness of 31% from NIR to DUV could be even now managed at this larger electric power situation, the normal output power with the DUV laser at 258 nm could possibly be more than 20 W, which might be a exceptional ability level for your DUV laser and bring on the unanticipated DUV laser machining results. Moreover, for top-energy 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.

LBO is usually a fantastic nonlinear crystal which is usually placed on the SHG in the NIR to the inexperienced. The DUV laser is usually recognized by two phases of SFG while in the LBO crystals considering the fact that there's no period-matching angle for LBO to transform the inexperienced laser at 515 nm or 532 nm to your DUV specifically by SHG [sixteen]. click here A short while ago, the NSBBF crystal has also revealed its opportunity to acquire a significant conversion effectiveness from 532 nm to 266 nm. The walk-off angle and deff of the NSBBF are Just about just like Individuals of CLBO [17].

The beam profile proven in Determine 7b shown a great beam top quality as one of the merits of Raman laser, which would be useful to crank out a 193-nm DUV laser with a top quality beam.
