Accelerated electrons for in situ peak intensity monitoring of tightly focused femtosecond laser radiation at high intensities

A simple technique for diagnosing the peak intensity of a tightly focused high-power femtosecond laser beam is proposed. The method is based on tracking the angular distribution of electrons directly accelerated in the waist of linearly polarized tightly focused radiation. Field ionization of a low...
