Based on the evidence-of-basic principle experiment, the conversion efficiency of 23% implied the potential for reaching higher-electric power at the 2nd Stokes wavelength of your Raman laser. If the pump laser of 1078 nm could possibly be acquired at the common electrical power of 50 W, the output energy of its 2nd Stokes wavelength at 1512 nm might be greater than 10 W. The design with the Raman laser cavity needs to be optimized in an effort to stay away from the hurt in the M1 and diamond surface area.
The crucial element problem of ultraviolet coherent mild supply generally concentrates on the event of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is among the situations for frequency transformation, so the growth, dimension, harm resistance, conversion efficiency and allowable parameter selection of nonlinear optical crystal are needed A growing number of.
Conversely, the beam top quality of the bigger electrical power DUV laser would become worse because of additional severe thermal and nonlinear outcomes. Therefore, the frequency conversion procedures ought to be very carefully meant to mitigate the aforementioned consequences. Thus, a higher-electrical power DUV laser with the FHG of 1 μm with a superb beam high-quality could be attained and can be advantageous for obtaining the shorter wavelength DUV lasers for instance 193 nm by SFG.
Both equally the 1040 check here nm and 1078 nm laser come from 1 twin-wavelength Yb-doped fiber laser. Every single laser is amplified by phases of fiber amplifier and Yb-doped components amplifier, respectively.
On one other aspect, the ability scaling in the NIR laser is yet another element to improve the average ability from the 193-nm DUV laser. As a result of lack of the high-ability amplification Remedy of your NIR laser (one example is at 1553 nm), nonlinear frequency processes for instance optical parameter oscillation (OPO) could possibly be placed on develop a wavelength converter by shifting the wavelength from one μm to the specified wavelength along with getting relative higher electricity [21]. Not too long ago, a diamond Raman laser confirmed its means in reaching a substantial energy plus a superior conversion efficiency on the 1st Stokes on the 1-μm laser [22,23], which means the possibility for being utilized from the 193-nm DUV laser technology as a consequence of its superior Raman attain and enormous frequency shift.
