The figures of optical system, longitudinal aberration and modulation transfer function (MTF) are given.
给出了光学系统图、纵向像差图及调制传递函数图。
Secondly, when the operation frequency is given, the dispersion relation between transverse wave vectors were analyzed with various longitudinal wave vector or modulation coefficients.
其次，在给定工作频率的情况下，分析了不同纵向波矢量和不同调制系数时的横向波矢量间布里渊区色散特性。
The results obtained in our work can be used in construction of a single longitudinal mode laser with enhance output and to suggest a new method of modulation for lasers.
它们可以用来得到较大输出能量的单纵模激光器和激光器的新的调制方法。
Then the simplified model for the LPFG is deduced with ignoring longitudinal coupling of modes and coupling of cladding modes themselves, and also assuming the modulation of refractive index exis...
忽略轴向的模式耦合以及包层模式之间的相互耦合作用，并认为折射率指数的调制只存在于纤芯中，建立了简化的长周期光纤光栅数学模型。
