We experimentally studied the influence of multi-transverse-mode pumping on the output characteristics of terahertz parametric oscillators (TPO). It was shown in our experiments that the beam quality of pumping beam affected the output power significantly. The THz output energy varied from 172nJ to 17nJ when M2 value of pump beam varied from 4.21 to 11.1 under the same pumping energy of 120mJ/pulse. The experiment results were explained by the gain enhancement effect in stimulated Raman emission under multi-mode pumping.
Keywords:terahertz wave parametric oscillator; pump mode; output characteristics
