Both of those the 1040 nm and 1078 nm laser come from a person dual-wavelength Yb-doped fiber laser. Each laser is amplified by phases of fiber amplifier and Yb-doped supplies amplifier, respectively.
On the other aspect, the facility scaling of the NIR laser is another factor to increase the regular electrical power from the 193-nm DUV laser. Due to deficiency of the substantial-electric power amplification solution of your NIR laser (for instance at 1553 nm), nonlinear frequency procedures such as optical parameter oscillation (OPO) can be applied to develop a wavelength converter by shifting the wavelength from 1 μm to the specified wavelength along with getting relative greater electric power [21]. Recently, a diamond Raman laser confirmed its ability in accomplishing a large ability as well as a superior conversion efficiency at the 1st Stokes on the one-μm laser [22,23], which implies the chance to become used inside the 193-nm DUV laser era thanks to its substantial Raman attain and large frequency shift.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics of the Nd:YAG elementary laser wavelength. In order to boost the destruction threshold, reduced CLBO floor roughness, by ultra-precision machining, is needed. Because the CLBO crystal has uncomplicated hydroscopic reaction and micro scratches in machining, extremely-specific machining of the CLBO crystal is a tough technical difficulty.

The conversion efficiency from basic NIR to DUV is from 5% to 36% according to the noted ends in Desk one. Increasing the conversion performance will decrease the load read more on the look and set up of the elemental laser amplifier and also the electric powered ability use. A very good beam high quality of the elemental laser will also contribute into the growing on the conversion performance as well as the suitable ability intensity from the NIR and environmentally friendly laser from the SHG and FHG procedure, respectively. The highest conversion efficiencies from NIR to green and green to DUV laser by utilization of CLBO crystal are 70% and close to fifty%, respectively [12], which corresponds into the conversion effectiveness of 35% from basic to DUV.
The development of your 193-nm laser was shown by phases of SFG. In order to scale the DUV laser electricity correctly, a brand new concept on the 193-nm DUV laser era is presented dependant on the diamond Raman laser.
