All-stable-point out ultraviolet lasers are actually greatly Employed in the fields of mechanical flaw detection, lithography, micromachining and drugs for some great benefits of smaller volume, lengthy existence, higher efficiency, superior beam excellent, extensive tuning and slim spectral line, etc. Employing higher power in the vicinity of-infrared coherent gentle source as the elemental frequency source based on nonlinear tuning technology, making ultraviolet coherent radiation by multistage frequency conversion is considered a very important technique to build the ultraviolet coherent light-weight resource.

We summarized the current enhancement standing from the large-power DUV laser both equally for the wavelength of FHG on the one-μm laser and at 193 nm. The new advancement of your reliable-point out/fiber laser, plus the nonlinear optical crystals, prompts don't just the common ability but additionally the beam high quality (coherence) with the DUV lasers to an unparalleled level.
The standard electric power with the NIR laser still has the opportunity for being enhanced to tens of watts for instance 70 W [26] In case the double-pass configuration can be utilized for the Yb:YAG SCF amplifier phase. Therefore, Should the conversion effectiveness of 31% from NIR to DUV can be continue to maintained at this increased power issue, the average output electricity of the DUV laser at 258 nm could possibly be much more than 20 W, which would become a extraordinary electrical power stage with the DUV laser and lead to the unanticipated DUV laser machining outcomes. In addition, for prime-electric power DUV laser, the UV destruction of the check here nonlinear crystal, such as the Home windows for CLBO crystal along with the mirrors, is another essential parameter for long-term and stable Procedure.

The two the 1040 nm and 1078 nm laser originate from just one dual-wavelength Yb-doped fiber laser. Each laser is amplified by phases of fiber amplifier and Yb-doped elements amplifier, respectively.
On one other aspect, the facility scaling on the NIR laser is another part to boost the ordinary electrical power of the 193-nm DUV laser. Due to lack of the substantial-ability amplification Remedy from the NIR laser (one example is at 1553 nm), nonlinear frequency procedures like optical parameter oscillation (OPO) may be placed on establish a wavelength converter by shifting the wavelength from one μm to the specified wavelength and getting relative greater electrical power [21]. Just lately, a diamond Raman laser confirmed its potential in achieving a large electric power in addition to a superior conversion performance for the 1st Stokes with the 1-μm laser [22,23], which implies the chance to get applied within the 193-nm DUV laser technology as a consequence of its substantial Raman obtain and large frequency change.

The heartbeat duration of the 2nd Stokes gentle was shortened to 5 ns as revealed in Figure 7a, a single-shot image from the oscilloscope, which happens to be a standard phenomenon in Raman laser [44] though the heartbeat period in the pump laser was ten ns.
This cookie is accustomed to record the input contents plus the progress in the enter type. It doesn't shop any particular data.
The beam profile proven in Determine 7b shown a very good beam high quality as among the list of deserves of Raman laser, which might be effective to generate a 193-nm DUV laser with a high quality beam.
Its UV absorption edge reaches one hundred eighty nm. The powerful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about twice as large as that of KDP. CLBO crystals could be grown from the stoichiometric soften with reduced viscosity.
