Based on the evidence-of-basic principle experiment, the conversion performance of 23% implied the opportunity of acquiring high-energy at the 2nd Stokes wavelength with the Raman laser. In case the pump laser of 1078 nm could possibly be attained at the average energy of 50 W, the output electric power of its 2nd Stokes wavelength at 1512 nm may be over ten W. The design in the Raman laser cavity should be optimized in an effort to stay away from the damage with the M1 and diamond surface.

The standard electric power from the NIR laser however has the possible to generally be enhanced to tens of watts like 70 W [26] In case the double-pass configuration may be used for your Yb:YAG SCF amplifier stage. As a result, In the event the conversion performance of 31% from NIR to DUV may very well be nonetheless taken care of at this better electricity problem, the common output electricity on the DUV laser at 258 nm may very well be in excess of twenty W, which might be described as a extraordinary electric power level for your DUV laser and cause the unanticipated DUV laser machining final results. In addition, for high-energy DUV laser, the UV damage of the nonlinear crystal, such as the Home windows for CLBO crystal plus the mirrors, is another vital parameter for long lasting and secure operation.

Both equally the 1040 nm and 1078 nm laser come from one dual-wavelength Yb-doped fiber laser. Just about every more info laser is amplified by phases of fiber amplifier and Yb-doped components amplifier, respectively.

In the scientific and industrial apps, the beam top quality in the DUV laser is additionally an essential parameter. Significantly, the beam good quality from the DUV laser dramatically influences the laser machining results. The beam excellent of your DUV laser is determined by that of the fundamental laser along with the crystal to the frequency conversion. A short while ago, a substantial-energy DUV laser (>ten W) at 258 nm was reported that has a beam good quality of M2 < one.5, which was generated by FHG of the Yb:YAG laser at 1030 nm using the CLBO crystal [13]. This laser would produce an improved laser machining outcome in comparison to the past DUV lasers with bigger M2.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics in the Nd:YAG basic laser wavelength. To be able to improve the damage threshold, lower CLBO surface area roughness, by ultra-precision machining, is necessary. Since the CLBO crystal has straightforward hydroscopic reaction and micro scratches in machining, extremely-specific machining of your CLBO crystal is usually a tricky complex issue.

The beam profile proven in Determine 7b shown a fantastic beam quality as one of many 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 180 nm. The efficient nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as substantial as that of KDP. CLBO crystals is often grown through the stoichiometric melt with lower viscosity.
