Nevertheless, to be able to system the crystal is rather State-of-the-art production techniques are expected. Considering that the dawn of this crystal, focusing on this obstacle, we are actually the one business on the planet which can be processed On this crystal.

The average power of your NIR laser however has the likely for being enhanced to tens of watts including 70 W [26] if the double-go configuration may very well be utilized with the Yb:YAG SCF amplifier stage. As a result, In the event the conversion efficiency of 31% from NIR to DUV may be nonetheless preserved at this higher electrical power ailment, the common output ability from the DUV laser at 258 nm might be a lot more than twenty W, which might certainly be a exceptional electricity stage with the DUV laser and bring on the unanticipated DUV laser machining results. In addition, for prime-electrical power DUV laser, the UV hurt on the nonlinear crystal, including the windows for CLBO crystal and also the mirrors, is another important parameter for long term and secure operation.

On the other facet, the power scaling with the NIR laser is an additional factor to boost the ordinary electrical power of the 193-nm DUV laser. Due to lack of the substantial-ability amplification Remedy with the NIR laser (such as at 1553 nm), nonlinear frequency processes for example optical click here parameter oscillation (OPO) may very well be placed on establish a wavelength converter by shifting the wavelength from 1 μm to the specified wavelength and obtaining relative greater electrical power [21]. Not long ago, a diamond Raman laser confirmed its skill in acquiring a superior ability and a superior conversion performance for the 1st Stokes on the 1-μm laser [22,23], which suggests the possibility to become used during the 193-nm DUV laser era as a result of its higher Raman attain and huge frequency change.

Tunable ultraviolet laser source according to strong-state dye laser technological innovation and CsLiB6O10 harmonic technology
The conversion efficiency from essential NIR to DUV is from 5% to 36% in accordance with the documented results in Desk one. Rising the conversion efficiency will decrease the stress on the design and set up of the basic laser amplifier along with the electrical energy usage. A fantastic beam high quality of the basic laser will also contribute on the increasing in the conversion effectiveness and the appropriate energy intensity on the NIR and inexperienced laser during the SHG and FHG process, respectively. The highest conversion efficiencies from NIR to green and green to DUV laser by use of CLBO crystal are 70% and around 50%, respectively [twelve], which corresponds into the conversion performance of 35% from basic to DUV.
