Fluence scan: an unexplored property of a laser beam

Popis výsledku v původním jazyce

We present an extended theoretical background of so-called fluence scan method, which is frequently being used for offline characterization of focused short-wavelength (EUV, X-ray) laser beams. The method exploits ablative imprints in various solids to visualize iso-fluence beam contours at different fluence and/or clip levels. An f-scan curve can be generated for a general non-Gaussian beam. As shown, f-scan encompasses important information about energy distribution within the beam profile, which mayplay an essential role in laser-matter interaction research employing intense non-ideal beams. We for the first time discuss fundamental properties of the f-scan function and its inverse counterpart. We extensively elucidate how it is related to the effective beam area, energy distribution, and to the so called Liu?s dependence. A new method of the effective area evaluation based on weighted inverse f-scan fit is introduced and applied to real data obtained at the SCSS facility.
