Having said that, as a way to system the crystal is extremely advanced production procedures are needed. Because the dawn of this crystal, focusing on this problem, we are actually the sole firm on the earth that may be processed During this crystal.

We summarized the current advancement position in the large-electrical power DUV laser both on the wavelength of FHG of your one-μm laser and at 193 nm. The the latest progress with the solid-point out/fiber laser, plus the nonlinear optical crystals, prompts don't just the average electric power but will also the beam high-quality (coherence) of the DUV lasers to an unparalleled stage.
The normal power of your NIR laser however has the likely for being enhanced to tens of watts for example 70 W [26] In the event the double-move configuration could possibly be utilized for that Yb:YAG SCF amplifier stage. That's why, When the conversion performance of 31% from NIR to DUV could possibly be continue to taken care of at this better energy situation, the standard output energy on the DUV laser at 258 nm could be over 20 W, which would become a amazing power level for the DUV laser and lead to the unanticipated DUV laser machining final results. Also, for prime-electricity DUV laser, the UV problems from the nonlinear crystal, including the Home windows for CLBO crystal as well as mirrors, is yet another critical parameter for long run and here stable operation.

On the opposite aspect, the power scaling from the NIR laser is yet another factor to boost the typical ability with the 193-nm DUV laser. A result of the lack of the superior-electricity amplification Answer with the NIR laser (for example at 1553 nm), nonlinear frequency processes which include optical parameter oscillation (OPO) may be placed on build a wavelength converter by shifting the wavelength from 1 μm to the specified wavelength and obtaining relative increased power [21]. Not too long ago, a diamond Raman laser confirmed its means in accomplishing a substantial power as well as a substantial conversion performance within the 1st Stokes from the one-μm laser [22,23], which means the possibility to be applied in the 193-nm DUV laser technology thanks to its superior Raman attain and enormous frequency shift.

The heartbeat period of the second Stokes mild was shortened to five ns as shown in Figure 7a, one-shot picture from your oscilloscope, which happens to be a common phenomenon in Raman laser [44] whilst the heartbeat length of your pump laser was 10 ns.
