The analytic expressions for steady-state electric field intensity and local scale length in a plasma irradiated by doublefrequency laser are derived. It is shown that the ponderomotive force due to double-frequency laser field would lead to the local density dip near critical surface and the anamolous increase and fluctuation of the critical scale length in some region of field intensity value.
