All-solid-condition ultraviolet lasers have already been widely used in the fields of mechanical flaw detection, lithography, micromachining and drugs for the benefits of little volume, lengthy existence, high efficiency, excellent beam high-quality, extensive tuning and slender spectral line, etcetera. Utilizing substantial electrical power in close proximity to-infrared coherent light-weight source as the elemental frequency source according to nonlinear tuning technology, producing ultraviolet coherent radiation by multistage frequency conversion is considered to be a significant strategy to develop the ultraviolet coherent light resource.

We summarized The existing growth status of the large-electricity DUV laser both of those for the wavelength of FHG of your one-μm laser and at 193 nm. The new advancement of the stable-state/fiber laser, and also the nonlinear optical crystals, prompts don't just the average power but in addition the beam excellent (coherence) in the DUV lasers to an unprecedented degree.
By way of example, the current concave OC could be replaced by a aircraft mirror which could mitigate the facility density around the surface area of M1 along with the diamond. In addition, employing large hurt threshold coatings for M1 and diamond would also Increase the output electric power with none damages. Then, the NIR laser in the 2nd Stokes wavelength may very well be high sufficient, along with its excellent beam high-quality, to make the ultimate DUV laser at 193 nm using a large ordinary electrical power.

Due to the thermal lens effect while in the solid-point out lasers, If your heating management is insufficient, It's not uncomplicated to obtain the solid-point out laser that has a higher electrical power plus a large beam top quality at the same time. Just lately, with the development of The skinny disk laser and one-crystal fiber (SCF) laser, a significant-electricity laser at the fundamental wavelength (one μm) had been realized with a good beam top quality In spite of a TEM00 mode beam [4,24], which would be excellent candidates for the basic of your DUV laser era. A further candidate for the elemental will be the high-electric power fiber laser which could be reached by coherent beam combination with M2 benefit fewer than 1.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the simplest non-linear crystal which generates ultraviolet harmonics of your Nd:YAG fundamental laser wavelength. In an effort to improve the injury threshold, minimal CLBO floor roughness, by extremely-precision machining, is necessary. Because the CLBO crystal has straightforward hydroscopic reaction and micro scratches in machining, ultra-precise machining on the CLBO crystal is usually a tough specialized dilemma.

The conversion performance from basic NIR to DUV is from 5% to 36% based on the claimed brings about Desk one. Escalating the conversion efficiency will lessen the burden on the design and set up of the fundamental laser amplifier plus the electric powered electrical power usage. An excellent beam excellent of the elemental laser can even lead to your raising of your conversion efficiency and also the right ability intensity of your NIR and inexperienced laser during the SHG and FHG procedure, respectively. The highest conversion efficiencies from NIR to inexperienced and environmentally friendly to DUV laser by use of CLBO crystal are 70% and around 50%, respectively [twelve], which corresponds on the conversion effectiveness of 35% from basic to DUV.
The event on the 193-nm laser was demonstrated by phases of SFG. In order to scale the DUV laser ability correctly, a different notion of the 193-nm DUV laser technology is offered determined by the diamond Raman laser.
