spontaneous radiation

基本解释

We prepared broadband source of transducer system in fiber grating by analyzing characteristics of amplification spontaneous radiation spectrum and LD drive in erbium doped fiber.
通过对掺铒光纤放大自发辐射谱特性和LD驱动电路的分析，最终研制出用于光纤光栅传感系统的宽带光源。
The results indicate that the reason of the asymmetry is from the shorter peak wavelength of the spontaneous radiation than the gain peak wavelength. The experiment confirmed the t…
结果表明，这种非对称分布可以认为是由于自发辐射峰值波长短于增益峰值波长所造成的。
Numerical results show how the intensity of emitted light varies from the spontaneous radiation, which undergoes amplification by small-signal gain, to the steady output due to the saturation effect.
结果显示了随机激光器中辐射光能量从自发辐射开始，经历小信号增益状态得到放大，再到由于增益饱和形成稳态输出的整个演化过程；
