According to the evidence-of-basic principle experiment, the conversion performance of 23% implied the opportunity of achieving higher-power at the second Stokes wavelength of the Raman laser. When the pump laser of 1078 nm could possibly be received at the common electrical power of 50 W, the output ability of its 2nd Stokes wavelength at 1512 nm can be in excess of 10 W. The look with the Raman laser cavity should be optimized so as to steer clear of the hurt from the M1 and diamond area.
By way of example, The existing concave OC could be replaced by a airplane mirror which could mitigate the power density about the floor of M1 and also the diamond. In addition, applying higher destruction threshold coatings for M1 and diamond would also Increase the output electricity with none damages. Then, the NIR laser for the 2nd Stokes wavelength could possibly be higher sufficient, along with its very good beam excellent, to produce the final DUV laser at 193 nm by using a higher average ability.
On the flip side, the beam good quality of the higher electric power DUV laser would turn out to be worse resulting from extra critical thermal and nonlinear effects. That's why, the frequency conversion processes should be diligently meant to mitigate the aforementioned consequences. So, a higher-power DUV laser on the FHG of 1 μm with a superb beam high quality may be received and may be effective for getting the shorter wavelength DUV lasers such as 193 nm by SFG.
Because of the thermal lens effect in the solid-point out lasers, If your heating management is insufficient, It is far from quick to get the strong-point out laser having a high electric power and also a large beam quality concurrently. Not too long ago, with the event of the thin disk laser and one-crystal fiber (SCF) laser, a substantial-energy laser at the elemental wavelength (1 μm) had been realized with a fantastic beam top quality Despite having a get more info TEM00 mode beam [4,24], which might be good candidates for the fundamental on the DUV laser technology. Another candidate for the fundamental would be the significant-power fiber laser which could be attained by coherent beam mixture with M2 worth a lot less than one.
On one other facet, the ability scaling on the NIR laser is an additional factor to raise the regular electricity in the 193-nm DUV laser. Mainly because of the not enough the higher-energy amplification solution from the NIR laser (such as at 1553 nm), nonlinear frequency procedures for example optical parameter oscillation (OPO) could possibly be placed on make a wavelength converter by shifting the wavelength from one μm to the desired wavelength and getting relative bigger power [21]. Not long ago, a diamond Raman laser showed its ability in achieving a significant electrical power in addition to a large conversion effectiveness within the 1st Stokes of the 1-μm laser [22,23], which suggests the likelihood being used in the 193-nm DUV laser generation due to its higher Raman acquire and large frequency shift.

While in the scientific and industrial purposes, the beam quality from the DUV laser is additionally a vital parameter. Specially, the beam good quality of the DUV laser considerably impacts the laser machining results. The beam top quality on the DUV laser is decided by that of the fundamental laser as well as crystal for your frequency conversion. Not long ago, a superior-electrical power DUV laser (>10 W) at 258 nm was reported having a beam top quality of M2 < one.five, which was produced by FHG of a Yb:YAG laser at 1030 nm using the CLBO crystal [13]. This laser would produce a greater laser machining result in comparison with the previous DUV lasers with more substantial M2.
You may additionally Test the achievable access through own account by logging in or/and Look at accessibility by way of your establishment.
Moreover, combining the strong-condition laser with other nonlinear procedure for example stimulated Raman scattering, NIR lasers might be attained at new wavelengths with substantial power and substantial beam excellent, which was tested with the evidence-of-principle experiment. This Raman laser scheme supplies a different route to the large-electricity DUV laser, especially at the wavelength of 193 nm.
Tunable ultraviolet laser resource based on strong-state dye laser technological innovation and CsLiB6O10 harmonic technology
Its UV absorption edge reaches 180 nm. The efficient nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as significant as that of KDP. CLBO crystals can be developed with the stoichiometric soften with decreased viscosity.
