In this paper, we extend our previous work and calculate the field structure and the conversion efficiency of the higher order harmonics emission. In calculation, the effect of density profile steepening in the vicinity of the critical density has been taken into account by assuming a bilinear density profile. The analytical results obtained can give a reasonable explanation to the physical phenomena observed in CO2-laser experiments.
