Results of the study of CsI luminescence excited by 58.5 eV photons of the XUV laser of LULI are presented. The energy of the exciting photons was sufficient for the creation of core holes at the 4d-iodine level. Following a single laser pulse luminescence spectra in the range 200 - 900 nm were detected. Using foil filters the density of excitation was varied from l09 to 1013 photons/cm2. The luminescence spectra measured following the laser pulse were substantially different from those measured using synchrotron radiation of the same energy or with X-rays. The following effect observed is discussed : manifestation of a new band attributed to the creation of complex defects (550 nm).
