All-reliable-condition ultraviolet lasers are commonly Utilized in the fields of mechanical flaw detection, lithography, micromachining and medication for the benefits of tiny volume, very long lifetime, high efficiency, great beam top quality, vast tuning and narrow spectral line, and so on. Utilizing significant electrical power around-infrared coherent mild resource as the basic frequency resource dependant on nonlinear tuning technology, producing ultraviolet coherent radiation by multistage frequency conversion is thought to be a vital method to build the ultraviolet coherent gentle resource.

In accordance with the proof-of-theory experiment, the conversion performance of 23% implied the potential of acquiring large-ability at the second Stokes wavelength with the Raman laser. When the pump laser of 1078 nm could possibly be acquired at the common electric power of fifty W, the output electricity of its 2nd Stokes wavelength at 1512 nm may very well be in excess of ten W. The design in the Raman laser cavity really should be optimized so that you can stay away from the damage of the M1 and diamond floor.
The standard electric power of the NIR laser however has the possible for being enhanced to tens of watts like 70 W [26] If your double-pass configuration may be utilized for the Yb:YAG SCF amplifier stage. Hence, In case the conversion efficiency of 31% from NIR to DUV may be however taken care of at this bigger electrical power ailment, the typical output energy of the DUV laser at 258 nm could possibly be more than 20 W, which would be described as a outstanding electrical power degree for that DUV laser and lead to the unanticipated DUV laser machining effects. Also, for top-power DUV laser, the UV harm of the nonlinear crystal, such as the windows for CLBO crystal as well as mirrors, is another important parameter for long term and secure operation.

LBO is also an outstanding nonlinear crystal which is often applied to the SHG from your NIR to your environmentally friendly. The DUV laser is generally realized by two levels of SFG within the LBO crystals given that there is not any phase-matching angle for LBO to transform the eco-friendly laser at 515 nm or 532 nm on the DUV directly by SHG [sixteen]. Lately, the NSBBF crystal has also proven its prospective to obtain a higher conversion performance from 532 nm to 266 nm. The wander-off angle and deff on the NSBBF are Pretty much just like Individuals of CLBO [seventeen].

During the scientific and industrial apps, the beam excellent on the DUV laser can be a crucial parameter. Specifically, the beam high quality from the DUV laser dramatically influences the laser machining outcomes. The beam quality on the DUV laser is decided by that of the fundamental laser as well as the crystal for the frequency conversion. A short while ago, a substantial-energy DUV laser (>ten W) at 258 nm was reported that has a beam high 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 result in an even better laser machining result in comparison to the former DUV lasers with bigger M2.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics with the Nd:YAG essential laser wavelength. In order to increase the injury threshold, low CLBO floor roughness, by ultra-precision machining, is necessary. Because the CLBO crystal has quick hydroscopic reaction and micro scratches in machining, ultra-specific machining of your CLBO crystal can be a tough complex problem.
The beam profile revealed in Determine 7b shown a very good beam high quality as one of several merits of Raman laser, which would be helpful to make a 193-nm DUV laser with a high quality beam.
The conversion effectiveness from fundamental NIR to DUV is from 5% to 36% in accordance with the noted brings about Table one. Growing the conversion effectiveness will lessen the stress on the design and setup of the basic laser amplifier and also the electric electric power consumption. An excellent beam high-quality of the fundamental laser may even lead into the growing in the conversion effectiveness together with the right power intensity of the NIR and green laser inside the SHG and FHG system, respectively. more info The highest conversion efficiencies from NIR to green and environmentally friendly to DUV laser by use of CLBO crystal are 70% and about fifty%, respectively [12], which corresponds for the conversion efficiency of 35% from essential to DUV.
The development on the 193-nm laser was shown by stages of SFG. In an effort to scale the DUV laser power properly, a whole new principle of your 193-nm DUV laser generation is presented determined by the diamond Raman laser.
