According to the proof-of-principle experiment, the conversion effectiveness of 23% implied the opportunity of reaching large-electric power at the next Stokes wavelength on the Raman laser. If your pump laser of 1078 nm could possibly be received at the normal ability of 50 W, the output electric power of its 2nd Stokes wavelength at 1512 nm might be more than ten W. The design from the Raman laser cavity needs to be optimized as a way to stay away from the injury on the M1 and diamond surface area.
The crucial element problem of ultraviolet coherent light-weight resource mainly focuses on the development of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is one of the situations for frequency transformation, so the growth, dimension, harm resistance, conversion efficiency and allowable parameter selection of nonlinear optical crystal are required Progressively more.

On the other facet, the ability scaling in the NIR laser is another aspect to enhance the normal electricity in the 193-nm DUV laser. Because of the not enough the substantial-energy amplification Option in the NIR laser (for example at 1553 nm), nonlinear frequency processes which include optical parameter oscillation (OPO) may be applied to create a wavelength converter by shifting the wavelength from one μm to the specified wavelength in addition to acquiring relative higher electrical power [21]. A short while ago, a diamond Raman laser showed its capacity in accomplishing a high energy plus a significant conversion performance within the 1st Stokes from the 1-μm laser [22,23], which implies the possibility to become applied in the 193-nm DUV laser technology because of its high Raman gain and enormous frequency change.

The heartbeat duration of the next Stokes light was shortened to 5 ns as revealed in Figure 7a, only one-shot image through the oscilloscope, that's a typical phenomenon in Raman laser [44] when the pulse length of your pump laser was 10 ns.

Tunable ultraviolet laser source according to sound-state dye laser engineering and CsLiB6O10 harmonic generation
The conversion efficiency from essential NIR to DUV is from 5% to 36% in accordance with the noted leads to Desk one. Escalating the conversion performance will reduce the load on the look and setup of the fundamental laser amplifier together with the electric electric power consumption. An excellent beam high-quality of the fundamental laser will click here even lead into the increasing in the conversion effectiveness together with the right power depth of the NIR and green laser within the SHG and FHG method, respectively. The highest conversion efficiencies from NIR to eco-friendly and eco-friendly to DUV laser by utilization of CLBO crystal are 70% and close to 50%, respectively [twelve], which corresponds to your conversion effectiveness of 35% from essential to DUV.
