摘要：
For the broadband laser obtained by chirped pulses stacking (CPS) method, the physical mechanism has been analyzed and the temporal shape and the spectrum distribution have been given. The effects of the intensity and bandwidth of the incident fundamental field on the third harmonic conversion efficiency of CPS laser using type I/II and type I/II/II angle-detuning schemes have been analyzed quantitatively. The numerical calculation results have been compared with those of temporal phase modulation (TPM) broadband laser. The results indicate that the I/II/II angle-detuning scheme can increase the third harmonic conversion efficiency obviously, and the third harmonic conversion efficiency of CPS laser can be increased more obviously than that of TPM laser.
