Spectral and time-resolved investigations of the back-scattered light from aluminium laser-produced plasmas at frequencies ωL and 2ωL are performed. Good correlation between maxima of the scattered light at ωL and minima at 2ωL was discovered. This correlation has been predicted by the theory. These experiments show that the spectrum width and intensity of the second harmonic essentially depend on the velocity of the expanding plasma.
