Abstract

We report here some observations and preliminary findings from a study focussed on the vacuum-UV (λ, 40 - 60 nm) radiation emitted during the interaction of 150 ps laser pulses (100 - 400 mJ) with copper pre-plasmas formed by an electro-optically synchronised (0.1 - 0.8 J, 8 ns) long pulse laser. We have observed significant gains in VUV flux that scale with inter-laser delay. We also report preliminary observations on total X-ray emission from the interaction of a superintense 80 fs, 200 mJ laser pulse at the UK ASTRA laser facility with a similar pre-plasma at irradiances approaching 10¹⁹ W/cm².
