The harmonic generation by resonant absorption in the laser-produced plasmas is analytically investigated by considering the steepened plasma density gradients in the vicinity of the critical density. The efficiency of the second-harmonic generation obtained is in agreement with experimental results. The calculation has also been extended to estimate the efficiency of the third harmonic generation.
