As compared to BBO it functions more substantial spectral and temperature acceptance, superior angle tolerance, along with a more compact wander-off angle. from 3289 $ supply

The average power on the NIR laser still has the likely to be enhanced to tens of watts for example 70 W [26] In case the double-pass configuration might be used for that Yb:YAG SCF amplifier stage. Hence, Should the conversion performance of 31% from NIR to DUV might be continue to taken care of at this bigger electrical power ailment, the typical output electric power from the DUV laser at 258 nm may be much more than 20 W, which would certainly be a remarkable electricity amount for the DUV laser and cause the unanticipated DUV laser machining success. Furthermore, for prime-electricity DUV laser, the UV problems on the nonlinear crystal, such as the windows for CLBO crystal and also the mirrors, is another essential parameter for long-term and secure Procedure.

On another aspect, the power scaling of the NIR laser is another component to enhance the regular electrical power of the 193-nm DUV laser. Due to the deficiency of the large-power amplification Option in the NIR laser (as an example at 1553 nm), nonlinear frequency processes for instance optical parameter oscillation (OPO) can be placed on establish a wavelength converter by shifting the wavelength from 1 μm to the specified wavelength and also getting relative better ability [21]. Not long ago, a diamond Raman laser confirmed its potential in achieving a large electric power along with a significant conversion performance on the 1st Stokes of your 1-μm laser [22,23], which suggests the chance to become applied during the 193-nm DUV laser generation as a result of its superior Raman get and enormous frequency change.

Tunable ultraviolet laser supply based on strong-condition dye laser technologies and CsLiB6O10 harmonic era
The conversion effectiveness from elementary NIR to DUV is from 5% to 36% according to the noted brings about Table one. Expanding the conversion performance will decrease the stress on the look and setup of the elemental laser amplifier along with the electrical electrical power use. A fantastic beam excellent of the elemental laser can more info even lead to your rising from the conversion effectiveness in addition to the suitable power intensity from the NIR and eco-friendly laser during the SHG and FHG method, respectively. The very best conversion efficiencies from NIR to environmentally friendly and eco-friendly to DUV laser by utilization of CLBO crystal are 70% and close to 50%, respectively [twelve], which corresponds into the conversion performance of 35% from essential to DUV.
