Based on the proof-of-basic principle experiment, the conversion efficiency of 23% implied the potential of obtaining higher-electrical power at the next Stokes wavelength from the Raman laser. In case the pump laser of 1078 nm may very well be received at the normal energy of 50 W, the output power of its 2nd Stokes wavelength at 1512 nm could be over 10 W. The design of the Raman laser cavity should be optimized in order to steer clear of the hurt in the M1 and diamond surface.
The key trouble of ultraviolet coherent light-weight source predominantly concentrates on the development of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is among the circumstances for frequency transformation, so the growth, sizing, damage resistance, conversion performance and allowable parameter number of nonlinear optical crystal are demanded Progressively more.
On the other hand, the beam excellent of this increased electricity DUV laser would turn into even worse as a result of extra significant thermal and nonlinear outcomes. As a result, the frequency conversion processes ought to be meticulously built to mitigate the aforementioned consequences. Thus, a higher-power DUV laser within the FHG of one μm with a very good beam high-quality could be attained and may be useful for acquiring the shorter wavelength DUV lasers including 193 nm by SFG.
The two the 1040 nm and 1078 nm laser come from one twin-wavelength Yb-doped fiber laser. Each laser is amplified by phases of fiber amplifier and Yb-doped components amplifier, respectively.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics on the Nd:YAG basic laser wavelength. In an effort to boost the injury threshold, reduced CLBO surface roughness, by extremely-precision machining, is needed. As the CLBO crystal has quick hydroscopic reaction and micro scratches in machining, ultra-exact machining from the CLBO crystal is a complicated complex problem.
Tunable ultraviolet laser supply based upon stable-condition dye laser know-how and CsLiB6O10 harmonic era
The conversion efficiency from essential NIR to DUV is from 5% to 36% in accordance with the noted brings about Table one. Increasing the conversion effectiveness will lessen the burden on the look and set up of the fundamental laser amplifier and also the electric electricity use. An excellent beam excellent of the elemental laser CLBO Crystal may also contribute towards the rising of your conversion performance in addition to the appropriate electricity depth on the NIR and environmentally friendly laser in the SHG and FHG process, respectively. The highest conversion efficiencies from NIR to green and green to DUV laser by usage of CLBO crystal are 70% and all-around fifty%, respectively [12], which corresponds towards the conversion efficiency of 35% from essential to DUV.
