This experiment the laser beam was focused on the surface of thin aluminum film of aluminum with thicknesses l0 = 0.1-25 μm at 0° or 45° incidence angle with an f/3 (f = 16.5 cm) off-axis parabolic mirror. The maximum focused intensity was 6.1018 W/cm2 for the fundamental frequency and 3.1018 W/cm2 for 2ω-0$/. The obtained data was analyzed in detail.
