Abstract
The frequency doubled laser pulses from the T3 laser system at the
Center for Ultrafast Optical Science of the University
Michigan1 (with energy up to 1 J, a pulse duration of 400 fs,
the wavelength is 0.53 m and the maximum intensity is
W/cm2) has been used to measure the light
transmitted through thin metal targets. The intensity contrast ratio
of the laser pulse was better than 10 - 9 which is low enough
to suggest the interaction with solid density plasma without
preplasma. We observed the transmittance of the laser pulse through
the aluminum foil with thickness up to 4
m and found that
this radiation is polarized and centered at 0.53
m. We
found that for 0.8
m thick foils the transmission was
anomalously high (
%) and can't be explained by
the skin effect for relativistic pulse.
