WebMar 19, 2024 · The experimental results verified that chromatic aberration in the laser system was almost fully compensated: the size of laser beam focused by an f/2.42 off-axis parabolic mirror was reduced tremendously from 32×18μm2 to about 4×4 μm2 at full width at half maximum (FWHM). 10 PDF WebAbstract Adaptive Optics (AO) loops are now widely implemented on high power laser chains. Their main goal is to optimize laser-matter interaction (gas or solid). One particular optimized parameter is the intensity at the focus of the off-axis parabola, which is the final optics seen by the laser. © 2024 IEEE PDF Article WebDec 1, 2024 · After optimization, the focal spot size (full width at half maximum, FWHM) is 3.3 μm × 4.0 μm in x-axis and y-axis directions and the enclosed energy in FWHM is 28% when an on-axis parabolic... grand coulee dam structure
