Based on the evidence-of-basic principle experiment, the conversion performance of 23% implied the potential of accomplishing high-electricity at the 2nd Stokes wavelength with the Raman laser. If your pump laser of 1078 nm could be received at the normal ability of fifty W, the output energy of its 2nd Stokes wavelength at 1512 nm may be in excess of ten W. The look on the Raman laser cavity need to be optimized so that you can steer clear of the hurt from the M1 and diamond area.
As an illustration, The present concave OC could be replaced by a airplane mirror which could mitigate the power density over the floor of M1 as well as diamond. Also, utilizing large harm threshold coatings for M1 and diamond would also Increase the output energy with no damages. Then, the NIR laser with the 2nd Stokes wavelength can be large enough, and also its good beam high-quality, to create the final DUV laser at 193 nm that has a large average electricity.

Due to the thermal lens effect in the good-condition lasers, if the heating administration is insufficient, It is far from effortless to obtain the reliable-state laser by using a higher electric power as well as a higher beam high quality at the same time. Lately, with the event of the thin disk laser and one-crystal fiber (SCF) laser, a higher-electric power laser at the fundamental wavelength (1 μm) were understood with an excellent beam high-quality Despite having a TEM00 method beam [4,24], which would be excellent candidates for the basic on the DUV laser era. A different applicant for the basic would be the significant-electric power fiber laser which may very well be realized by coherent beam mix with M2 benefit a lot less than one.
On another side, the power scaling of the NIR laser is yet another component to enhance the normal electricity in the 193-nm DUV laser. As a result of lack of the high-electrical power amplification solution of your NIR laser (for instance at 1553 nm), nonlinear frequency procedures such as optical parameter oscillation (OPO) may very well be placed on develop a wavelength converter by shifting the wavelength from one μm to the specified wavelength along with acquiring relative higher electrical power [21]. A short while ago, a diamond Raman laser showed its capacity in accomplishing a high here electricity as well as a superior conversion efficiency in the 1st Stokes on the one-μm laser [22,23], which suggests the chance to generally be applied within the 193-nm DUV laser generation as a consequence of its high Raman acquire and enormous frequency change.

The heartbeat duration of the next Stokes light-weight was shortened to five ns as demonstrated in Figure 7a, a single-shot image within the oscilloscope, that's a common phenomenon in Raman laser [44] whilst the heart beat duration on the pump laser was ten ns.
Cesium Lithium Borate (CsLiB6O10 or CLBO) is the most effective non-linear crystal which generates ultraviolet harmonics in the Nd:YAG basic laser wavelength. As a way to increase the hurt threshold, lower CLBO surface area roughness, by ultra-precision machining, is necessary. Since the CLBO crystal has straightforward hydroscopic response and micro scratches in machining, ultra-precise machining with the CLBO crystal can be a complicated complex difficulty.
The beam profile demonstrated in Determine 7b shown a great beam excellent as one of the merits of Raman laser, which would be useful to crank out a 193-nm DUV laser with a top quality beam.
Its UV absorption edge reaches one hundred eighty nm. The efficient nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as massive as that of KDP. CLBO crystals could be developed through the stoichiometric melt with decreased viscosity.
