Soft x-ray emission from 170 ps laser-produced plasmas formed on cerium-doped
borosilicate glasses has been recorded in the 7–17 nm region using a 2 m grazing
incidence vacuum spectrograph. Broadband spectra have been recorded on photographic
plates, while intensity comparisons have been made using an absolutely calibrated, extreme
ultraviolet sensitive photodiode. The use of a laser prepulse to prime the target has been
seen to enhance the emission with the maximum flux produced at an interpulse delay of 5.1 …
