Abstract: (3619 Views)
In this paper, the absorption coefficient of a laser produced copper plasma by a focused beam of 28 ns Nd:YAG laser has been measured by means of laser beam of a He-Ne laser or second harmonic of a Nd:YAG laser probe at 633 nm and 532 nm, respectively. The measurements have been performed in air environment at 1 atmosphere pressure with different state of probe beam polarization. The probe beams have been focused and collimated by a pair of confocal 5 cm convex lenses. The displacement resolution of the focused probe beam from the focused position of the interaction beam on the surface of target is 1 mm. By this means, the velocity of ions in expanding plasma was measured that its value is 5×104 cm/s.
