The proportion between the thermalization process and diffusion process possess in all the decay process is determined by photon energy of excitation.
载流子的热弛豫过程与扩散过程在整个衰减过程中所占的比例，取决于激发光子的能量。

And the decay rate of these deviations depends on not only the carrier lifetime but also the photon lifetime, which is different from that of an ordinary diode laser experiencing turn-on process.
