All-strong-state ultraviolet lasers have already been commonly Employed in the fields of mechanical flaw detection, lithography, micromachining and medication for the benefits of smaller quantity, prolonged lifetime, large performance, superior beam excellent, extensive tuning and narrow spectral line, etcetera. Employing significant ability in the vicinity of-infrared coherent mild resource as the fundamental frequency source based on nonlinear tuning technology, making ultraviolet coherent radiation by multistage frequency conversion is considered a very important strategy to develop the ultraviolet coherent mild resource.

We summarized The present improvement status of your significant-electricity DUV laser the two in the wavelength of FHG of your 1-μm laser and at 193 nm. The recent improvement with the sound-condition/fiber laser, along with the nonlinear optical crystals, prompts not simply the average electrical power but will also the beam high quality (coherence) in the DUV lasers to an unprecedented stage.
For instance, The existing concave OC could get replaced by a plane mirror which could mitigate the facility density to the surface area of M1 and also the diamond. What's more, working with large problems threshold coatings for M1 and diamond would also Enhance the output ability with no damages. Then, the NIR laser for the 2nd Stokes wavelength might be substantial sufficient, and also its excellent beam excellent, to make the ultimate DUV laser at 193 nm by using a high ordinary electric power.

As a result of thermal lens effect in the good-condition lasers, When the heating administration is inadequate, It's not at all straightforward to acquire the sound-point out laser using a high electric power along with a significant beam high-quality concurrently. Recently, with the development of The skinny disk laser and solitary-crystal fiber (SCF) laser, a high-electric power laser at the elemental wavelength (1 μm) had been understood with a good beam good quality In spite of a TEM00 manner beam [four,24], which would be great candidates for the basic on the DUV laser technology. An additional candidate for the fundamental may be the large-electricity fiber laser which may be reached by coherent beam mixture with M2 value lower than 1.
On the opposite aspect, the ability scaling with the NIR laser is yet another part to improve the regular electricity in the 193-nm DUV laser. As a result of lack of the high-electric power amplification Remedy of your NIR laser (by way of example at 1553 nm), nonlinear frequency processes for instance optical parameter oscillation (OPO) could possibly be applied to produce a wavelength converter by shifting the wavelength from 1 μm to the desired wavelength and obtaining relative increased power [21]. Not too long ago, a diamond Raman laser confirmed its means in reaching a substantial electric power and also a higher conversion effectiveness at the 1st Stokes on the one-μm laser [22,23], which means the chance to generally be applied within the 193-nm DUV laser generation as a result of its substantial Raman get and huge frequency shift.

The pulse period of the next Stokes light was shortened to five ns as proven in Figure 7a, only one-shot photo from your oscilloscope, which is a standard phenomenon in Raman laser [44] when the heartbeat duration with the pump laser was 10 ns.

The conversion effectiveness from fundamental NIR to DUV is from five% to 36% based on the claimed leads to Desk one. Rising the conversion performance will reduce the load on the look and setup of the elemental laser amplifier in addition to the electric powered energy intake. A very good beam top quality of the basic laser will likely contribute towards the increasing in the conversion effectiveness and the right power depth of your NIR and environmentally friendly laser in the SHG and FHG process, respectively. The best conversion efficiencies from NIR to inexperienced and inexperienced to DUV laser by use of CLBO crystal are 70% and about fifty%, respectively [twelve], which corresponds for the conversion efficiency of 35% from essential to DUV.
