The temporal behavior of gadolinium (Gd) laser-produced plasmas has been studied using a modified grazing incidence spectrometer which allows to capture the evolution plasma with spectral and resolution 0.1 nm 1 ns, respectively. Experimental results indicate that soft X-ray emission follows laser pulse at high power density Ф = 4.4×10 12 W/cm 2 in lasts for 7.5 ns (at FWHM) whereas 5.4×10 11 7.6×10 10 only 4 2.5 respectively , s e are horter than duration due lower electron temperatures achieved generation. Lower Gd ion stages ranging from 11+ – 14+ also found contribute over time. Received: 08 November 2013; Revised: 09 May 2014; Accepted: 2014
