1) spontaneous emission lifetime modulation
自发发射寿命调制
1.
Supposing that input modulation signal is actual phonetic signal and its adjoint noise is additive white noise, for spontaneous emission lifetime modulation and photon lifetime modulation, we derive signal-to-noise ratio (SNR) in various parameters through frequency domain analysis against laser in the premiss of large input SNR.

补充资料：自发发射
分子式：
CAS号：
性质：即使不存在外电磁场的微扰作用，仍能发生的发射模式。在n态与m态之间的跃迁，由自发发射的爱因斯坦系数Anm所决定。
