摘要：
We experimentally study the influence of multi-transverse-mode pumping on the output characteristics of terahertz parametric oscillators (TPO). We show in our experiments that the quality of the pumping beam affected the output power significantly. The terahertz output energy varied from 172 nJ to 17 nJ when the M-2 value of the pump beam varied from 4.21 to 11.1 under the same pumping energy of 120 mJ/pulse. The experimental results were explained by the gain enhancement effect in stimulated Raman emission under multi-mode pumping.
