| Abstract: | The main characteristics of the third harmonic emission generated by
femtosecond laser pulses propagating in air are investigated by numerically
solving the coupled nonlinear Schr?dinger equations. Strong third
harmonic emission is observed with a maximum conversion efficiency as high
as 0.43%. The on-axis phase difference between fundamental beam and third
harmonic is investigated. The result is in good agreement with the
phase-locking mechanism. Dependence of the conversion of third harmonic
emission on focusing conditions is also studied. The results are also
compared with those of experiments. |
