发现在不同的注入光强度和波长下，激光器的调制带宽和弛豫振荡峰频率会发生变化。
The modulation bandwidth and the relaxation oscillation frequencies of the laser are quite different at different injection powers and wavelengths.
分析表明，交叉弛豫随激发场强度增大，并导致偏振因子随激发场入射脉冲面积减小。
It was revealed that the cross relaxation increased with intensity of the excitation, which resulted in the decrease of polarization factor with the input pulse area.
激光达到饱和强度时，上能级弛豫速率等于受激跃迁几率。
The relaxation rate of upper level is equal to the transition probability of stimulated emission.
