We have studied parametric heating caused by electric field of strong laser with frequence which is a little higher than plasma frequence(w₀=1.1W_p)by use one and half dimensional CIC scheme. Results shown that both the ion-acoustic instabilities and the oscillation two-stream instabilities are stimulated together, nonlinear saturation show some fine structures, plasma is heated strongly and tur-blent spectra after saturetion fllows a typical power law.
