Optical emission from Al target irradiated by FLASH
Original language description
The following text touches on some peculiarities in optical emission spectroscopy results from experiments on the free-electron laser FLASH. Aluminum targets were irradiated with 13.5 nm ~25 fs pulses at intensities of 1013 and 1016 W/cm2 (20 and 1µm foci). Surprisingly, only neutral atom lines for the case with wider focus and traces of ion lines in the tighter focus case were observed with the optical emission spectroscopy (200-600 nm range). The motivating idea behind this work is the suggestion by Zastrau that the optical spectrometer sees only emissions from a cold expanding lower-density (< 1022 cm-3) plasma plume. In this contribution the notion of UV range screening is analyzed in detail.n
