Simultaneous Measurement of Absorption and X-Ray Emission from Preformed Plasma Generated by Ultrashort Prepulse

概要
- 論文の詳細を見る
The first simultaneous measurement of the reflectivity and the X-ray yield from the preformed plasma was performed with a fine temporal resolution between the prepulse and the main ionization pulse. Enhancement of the X-ray emission at the long temporal separation is due to the increase of the absorption of an intense ultrashort laser pulse in a preformed plasma with a scale length longer than laser wavelength. The maximum response of X-ray emission at 22.5° and the weak dependence on the polarization of input laser light infer that collisional absorption with additional resonance absorption in a nonuniform critical density profile is the main absorption process in the preformed plasma.
