Nevertheless, as a way to procedure the crystal is rather Superior production methods are essential. For the reason that dawn of the crystal, focusing on this challenge, we at the moment are the only real organization on the earth that can be processed On this crystal.
As compared to BBO it attributes more substantial spectral and temperature acceptance, superior angle tolerance, in addition to a smaller sized walk-off angle. from 3289 $ delivery
In accordance with the evidence-of-principle experiment, the conversion performance of 23% implied the potential for reaching higher-electrical power at the second Stokes wavelength from the Raman laser. When the pump laser of 1078 nm might be attained at the standard ability of fifty W, the output ability of its 2nd Stokes wavelength at 1512 nm could be much more than 10 W. The look of the Raman laser cavity really should be optimized as a way to steer clear of the harm with the M1 and diamond surface.
The standard electrical power of your NIR laser nevertheless has the opportunity for being enhanced to tens of watts such as 70 W [26] In case the double-go configuration might be used to the Yb:YAG SCF amplifier stage. That's why, In case the conversion performance of 31% from NIR to DUV may be still maintained at this increased ability situation, the common output electric power from the DUV laser at 258 nm can be more than twenty W, which would be a amazing energy amount for the DUV laser and cause the unanticipated DUV laser machining effects. What's more, for prime-electric power DUV laser, the UV problems with the nonlinear crystal, including the windows for CLBO crystal plus the mirrors, is an additional critical parameter for long run and secure Procedure.

On another side, the facility scaling with the NIR laser is an additional facet to boost the average ability with the click here 193-nm DUV laser. Due to lack of the significant-electricity amplification Answer from the NIR laser (for instance at 1553 nm), nonlinear frequency procedures including optical parameter oscillation (OPO) could possibly be placed on develop a wavelength converter by shifting the wavelength from one μm to the desired wavelength and also getting relative larger electric power [21]. Lately, a diamond Raman laser confirmed its means in attaining a significant ability along with a large conversion effectiveness with the 1st Stokes with the one-μm laser [22,23], which suggests the chance to be used in the 193-nm DUV laser technology due to its high Raman acquire and large frequency shift.

You might also Test the probable obtain via individual account by logging in or/and check access by your institution.
Also, combining the sound-point out laser with other nonlinear method such as stimulated Raman scattering, NIR lasers may be achieved at new wavelengths with substantial power and large beam excellent, which was analyzed from the proof-of-theory experiment. This Raman laser scheme gives a whole new path to the substantial-electric power DUV laser, Primarily in the wavelength of 193 nm.

The conversion efficiency from essential NIR to DUV is from 5% to 36% according to the described results in Desk one. Rising the conversion efficiency will decrease the stress on the look and setup of the basic laser amplifier along with the electric powered electrical power intake. An excellent beam high-quality of the fundamental laser can even contribute for the expanding from the conversion effectiveness and the appropriate electrical power intensity on the NIR and inexperienced laser inside the SHG and FHG course of action, respectively. The best conversion efficiencies from NIR to environmentally friendly and environmentally friendly to DUV laser by usage of CLBO crystal are 70% and around fifty%, respectively [12], which corresponds for the conversion efficiency of 35% from fundamental to DUV.
The development on the 193-nm laser was shown by stages of SFG. So that you can scale the DUV laser electrical power successfully, a different idea with the 193-nm DUV laser technology is presented according to the diamond Raman laser.
