We present the results of experimental investigations of terahertz radiation generation conversion efficiency in an OH1 nonlinear organic crystal pumped by femtosecond laser pulses at 1240 nm wavelength. An influence of OH1 crystal thickness on the terahertz generation by optical rectification method was studied. It is shown that the optimal crystal thickness for the maximum conversion efficiency is 1 mm, which agrees with the previously made theoretical estimates.
我们展示了在 1240nm 波长的飞秒激光脉冲泵浦下，OH1 非线性有机晶体中太赫兹辐射产生转换效率的实验研究结果。研究了 OH1 晶体厚度对光整流法太赫兹产生的影响。结果表明，对于最大转换效率的最佳晶体厚度为 1mm，这与之前的理论估计相符。
