We summarized the current development position on the large-ability DUV laser both of those in the wavelength of FHG on the 1-μm laser and at 193 nm. The modern progress of your strong-condition/fiber laser, as well as the nonlinear optical crystals, prompts don't just the standard electric power and also the beam high quality (coherence) in the DUV lasers to an unprecedented stage.
The average electric power from the NIR laser still has the likely to generally be improved to tens of watts like 70 W [26] In the event the double-pass configuration could possibly be utilized with the Yb:YAG SCF amplifier phase. Therefore, If your conversion effectiveness of 31% from NIR to DUV could be even now managed at this higher power condition, the standard output electricity from the DUV laser at 258 nm can be more than twenty W, which would become a remarkable electrical power level for that DUV laser and result in the unanticipated DUV laser machining effects. Furthermore, for prime-power DUV laser, the UV harm of your nonlinear crystal, such as the Home windows for CLBO crystal plus the mirrors, is yet another significant parameter for long-lasting and steady Procedure.

Both equally the 1040 nm and 1078 nm laser come from a person dual-wavelength Yb-doped fiber laser. Each more info and every laser is amplified by phases of fiber amplifier and Yb-doped elements amplifier, respectively.

Tunable ultraviolet laser resource based upon sound-point out dye laser technologies and CsLiB6O10 harmonic generation
The conversion efficiency from essential NIR to DUV is from 5% to 36% based on the claimed ends in Desk one. Escalating the conversion performance will lessen the burden on the design and setup of the elemental laser amplifier and also the electric powered electrical power usage. A fantastic beam excellent of the fundamental laser can even add on the increasing on the conversion effectiveness along with the suitable power depth from the NIR and environmentally friendly laser within the SHG and FHG procedure, respectively. The highest conversion efficiencies from NIR to environmentally friendly and inexperienced to DUV laser by usage of CLBO crystal are 70% and close to 50%, respectively [12], which corresponds on the conversion effectiveness of 35% from fundamental to DUV.
