All-reliable-point out ultraviolet lasers have been extensively Utilized in the fields of mechanical flaw detection, lithography, micromachining and medication for some great benefits of compact quantity, lengthy lifetime, superior effectiveness, fantastic beam good quality, wide tuning and narrow spectral line, and many others. Using high power in the vicinity of-infrared coherent mild resource as the fundamental frequency source dependant on nonlinear tuning engineering, making ultraviolet coherent radiation by multistage frequency conversion is regarded as a very important way to establish the ultraviolet coherent gentle supply.

The true secret problem of ultraviolet coherent mild resource primarily focuses on the event of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is amongst the problems for frequency transformation, so The expansion, dimensions, harm resistance, conversion performance and allowable parameter variety of nonlinear optical crystal are essential more and more.
On the other hand, the beam top quality of the larger ability DUV laser would grow to be worse because of extra significant thermal and nonlinear effects. Hence, the frequency conversion procedures need to be very carefully designed to mitigate the aforementioned effects. So, a higher-electric power DUV laser for the FHG of 1 μm with a very good beam top quality might be received and may be advantageous for getting the shorter wavelength DUV lasers which include 193 nm by SFG.
Equally the 1040 nm and 1078 nm laser originate from one particular dual-wavelength Yb-doped fiber laser. Every laser is amplified by stages of fiber amplifier and Yb-doped supplies amplifier, respectively.
