我们研究了相干放大双光子发射的效率如何取决于两个发射光子之一的频率，即信号光子。这是在5.048 - 10.21的波长范围内通过对氢的振动跃迁完成的。效率随信号光子频率的增加而增加。考虑到实验误差，我们的结果与目前实验条件下的理论预测一致。本研究通过实验证明了相干放大双光子发射的频率依赖性，并展示了其作为光源的潜力。
We investigate how the efficiency of coherently amplified two-photon emission depends on the frequency of one of the two emitted photons, namely the signal photon. This is done over the wavelength range of 5.048–10.21by using the vibrational transition of parahydrogen. The efficiency increases with the frequency of the signal photon. Considering experimental errors, our results are consistent with the theoretical prediction for the present experimental conditions. This study is an experimental demonstration of the frequency dependence of coherently amplified two-photon emission, and also presents its potential as a light source.
