The absorption, spontaneous emission and stimulated emission are discussed respectively.
分别考虑了吸收、自发辐射和受激辐射诸情况。
Time behaviors of the stimulated emission under relatively high pumping intensity, spontaneous emission, and laser pulses were compared, and hence the stimulated emission of ZnO thin films was proved.
比较了较高激发密度下的受激发射、自发发射和激光脉冲的时间特性，这些都证实了该发射是受激发射。
The orbits of an electron in self-fields, linear wiggler and axial fields are calculated. Then the spontaneous emission coefficient and the growth rate of the stimulated scattering are obtained.
本文计算了在平衡自场、线性摆动器场和轴向磁场作用下的电子轨道，并由此求得有线性摆动器的自由电子激光器的自发辐射和受激辐射。
