本文提出了一种半导体激光器噪声模型，该模型以载流子密度为动力学变量，并考虑了载流子密度与折射率的关系。货车der Pol激光噪声模型是这种处理的一个特例。所有的激光光谱的表达式进行了计算，并与他们的货车德波尔同行。功率波动谱和频率波动谱表现出对应于弛豫共振的共振，并且场谱包含精细结构，类似于由载波信号的谐波频率调制产生的边带。载波噪声在确定场谱线宽的作用也被认为是。
A model of semiconductor laser noise is presented which includes the carrier density as a dynamical variable and the carrier density dependence of the refractive index. The Van der Pol laser noise model is shown to he a special case of this treatment. Expressions are calculated for all laser spectra and compared with their Van der Pol counterparts. The power fluctuations spectrum and the frequency fluctuations spectrum exhibit a resonance corresponding to the relaxation resonance and the field spectrum contains fine structure, similar to sidebands which result from harmonic frequency modulation of a carrier signal. The role of carrier noise in determining the field spectrum linewidth is also considered.
