From the scientific and industrial programs, the beam excellent of the DUV laser is usually a significant parameter. Specifically, the beam top quality from the DUV laser substantially impacts the laser machining effects. The beam high quality with the DUV laser is set by that of the elemental laser along with the crystal for that frequency conversion. Lately, a higher-electricity DUV laser (>10 W) at 258 nm was described with a beam top quality of M2 < 1.five, which was created by FHG of the Yb:YAG laser at 1030 nm utilizing the CLBO crystal [13]. This laser would bring on a better laser machining consequence as compared to the preceding DUV lasers with bigger M2.
The heart beat duration of the next Stokes gentle was shortened to five ns as demonstrated in Figure 7a, only one-shot photograph within the oscilloscope, and that is a standard phenomenon in Raman laser [forty four] even though the pulse duration in the pump laser was 10 ns.
Cesium Lithium Borate (CsLiB6O10 or CLBO) is the most effective non-linear crystal which generates ultraviolet harmonics of your Nd:YAG basic laser wavelength. So as to greatly enhance the destruction threshold, low CLBO surface area roughness, by extremely-precision machining, is required. Since the CLBO crystal has quick hydroscopic response and micro scratches in machining, ultra-precise machining in the CLBO crystal is often a tricky complex challenge.
Tunable ultraviolet laser supply based on stable-state dye laser know-how and CsLiB6O10 harmonic generation
Its UV get more info absorption edge reaches one hundred eighty nm. The effective nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as massive as that of KDP. CLBO crystals is usually developed from your stoichiometric melt with reduced viscosity.
