Rv. Volkov et al., EVOLUTION OF A HIGH-TEMPERATURE FEMTOSECO ND SURFACE PLASMA, RECORDEDWITH TIME RESOLUTION, Kvantovaa elektronika, 22(9), 1995, pp. 909-912
The experiments are described involving the generation (and subsequent
probing) of a high-temperature surface plasma produced by 300 fs puls
es of 5 . 10(15) W/cm(2) intensity. An optical image of the plasma was
formed. This made it possible to achieve not only temporal but also s
patial resolution, and to determine the dynamics of the transverse str
ucture of the plasma From reflection of a probe pulse. The recorded pl
asma temperature was 140 eV and the expansion velocity was of the orde
r of 10(7) cm/s.
