Nevertheless, to be able to system the crystal may be very Superior manufacturing methods are necessary. Because the dawn of this crystal, focusing on this challenge, we are actually the only real company on the earth that may be processed In this particular crystal.

According to the proof-of-principle experiment, the conversion effectiveness of 23% implied the potential for achieving large-electricity at the second Stokes wavelength in the Raman laser. In case the pump laser of 1078 nm may very well be attained at the standard power of 50 W, the output energy of its 2nd Stokes wavelength at 1512 nm could possibly be over 10 W. The look with the Raman laser cavity really should be optimized so as to stay away from the injury of the M1 and diamond area.
The main element trouble of ultraviolet coherent light-weight resource mainly concentrates on the event of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal has become the disorders for frequency transformation, so The expansion, sizing, hurt resistance, conversion efficiency and allowable parameter selection of nonlinear optical crystal are needed more and more.
On the other hand, the beam good quality of the larger ability DUV laser would grow to be even worse due to a lot more serious thermal and nonlinear results. Hence, the frequency conversion processes really should be carefully created to mitigate the aforementioned outcomes. Consequently, a superior-power DUV laser in the FHG of 1 μm with a great beam high-quality can be acquired and may be effective for getting the shorter wavelength DUV lasers for instance 193 nm by SFG.
Both equally the 1040 nm and 1078 nm laser come from 1 twin-wavelength Yb-doped fiber laser. Just about every laser is amplified by stages of fiber amplifier and Yb-doped products amplifier, respectively.

The pulse length of the second Stokes gentle was shortened to 5 ns as demonstrated in Determine 7a, an individual-shot picture with the oscilloscope, that is a typical phenomenon in Raman laser [forty four] although the heart beat duration on the pump laser was ten ns.
Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics of your Nd:YAG basic laser wavelength. So that you can increase the injury threshold, reduced CLBO surface roughness, by extremely-precision machining, is required. Because the CLBO crystal has quick hydroscopic reaction and micro scratches in machining, ultra-exact machining in the CLBO crystal is a complicated complex issue.
Tunable ultraviolet laser source depending on reliable-condition dye laser technological know-how and CsLiB6O10 harmonic technology
