Khattak, F.Y., Clarke, R.J., Divall, E.J. et al. (12 more authors) (2005) Enhanced He-alpha emission from "smoked" Ti targets irradiated with 400nm, 45 fs laser pulses. Europhysics Letters. pp. 242-248. ISSN 1286-4854
Abstract
We present a study of He-like 1s(2)-1s2p line emission from solid and low-density Ti targets under similar or equal to 45 fs laser pulse irradiation with a frequency doubled Ti: Sapphire laser. By varying the beam spot, the intensity on target was varied from 10(15) W/cm(2) to 10(19) W/cm(2). At best focus, low density "smoked" Ti targets yield similar to 20 times more He-alpha than the foil targets when irradiated at an angle of 45 degrees with s-polarized pulses. The duration of He-alpha emission from smoked targets, measured with a fast streak camera, was similar to that from Ti foils.
