All-sound-condition ultraviolet lasers are already commonly Utilized in the fields of mechanical flaw detection, lithography, micromachining and medication for the benefits of tiny volume, long existence, high performance, good beam good quality, vast tuning and slender spectral line, etcetera. Utilizing higher energy in the vicinity of-infrared coherent light supply as the basic frequency resource according to nonlinear tuning know-how, generating ultraviolet coherent radiation by multistage frequency conversion is regarded as a crucial solution to develop the ultraviolet coherent mild supply.

In accordance with the evidence-of-basic principle experiment, the conversion efficiency of 23% implied the potential of accomplishing superior-power at the next Stokes wavelength with the Raman laser. Should the pump laser of 1078 nm can be attained at the average energy of 50 W, the output electrical power of its 2nd Stokes wavelength at 1512 nm may be in excess of ten W. The look of the Raman laser cavity need to be optimized so as to steer clear of the hurt from the M1 and diamond surface area.
The true secret problem of ultraviolet coherent light resource largely focuses on the development of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is amongst the circumstances for frequency transformation, so The expansion, dimensions, problems resistance, conversion performance and allowable parameter number of nonlinear optical crystal are demanded more and more.

As a result of thermal lens result within the good-condition lasers, When the heating administration is insufficient, it is not uncomplicated to obtain the stable-state laser that has a higher electric power along with a significant beam quality simultaneously. Not long ago, with the development of the thin disk laser and single-crystal fiber (SCF) laser, a superior-energy laser at the basic wavelength (one μm) were realized with a superb beam quality Despite a TEM00 mode beam [4,24], which would be great candidates for the elemental of the DUV laser technology. An additional candidate for the fundamental will be the substantial-electricity fiber laser which may very well be achieved by coherent beam mix with M2 worth lower than 1.

During 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 has an effect on the laser machining benefits. The beam top quality with the DUV laser is set by that of the fundamental laser plus the crystal to the frequency conversion. Lately, a superior-electricity DUV laser (>ten W) at 258 nm was noted with a beam good quality of M2 < one.5, which was produced by FHG of the Yb:YAG laser at 1030 nm using the CLBO crystal [13]. This laser would result in a greater laser machining final result when compared with the former DUV lasers with bigger M2.
