Examples
- Effects of dispersion decreasing and loss on transmission of bragg solitons in fiber bragg gratings is analyzed by simulating numerically the transform of bragg solitons
结果表明，光栅色散渐减使脉冲的峰值增大，光栅损耗使脉冲展宽，两者对布拉格孤子在光纤光栅中的传输具有互补性，即两者对布拉格孤子的传输作用相反。 - As we known that the laser pulse energy will be attenuated in the turbid media and the pulse shape will be changed by scattering and absorption . besides , the ultra short laser pulse will be widened by the diffusive scattering
由于超短脉冲激光在混浊介质中传输时，将因漫散射而使脉冲展宽，因此漫反射、漫透射光中必然含有介质光学特征的信息。 - We have calculated and plotted the curves of the refractive index , group velocity index , lowest - order and second - order dispersion indexes as a function of wavelength . the lowest - order and higher - order dispersion - induced broadening and deforming of light pulses is analyzed for various pulse shapes , such as gaussian , super - gaussian and hyperbolic secant pulses
给出了折射率、群速指数、低阶和二阶色散系数随波长变化的关系曲线，研究了高斯脉冲、超高斯脉冲和双曲正割脉冲等超短脉冲在clbo晶体中传播时，由于低阶色散和高阶色散引起的脉冲展宽和形变。 - Based on the theory mode , the delay time between the beginning of optical illumination and the onset of lock - on switching was calculated , and the transiting speed of electrons , the traversing velocity of the current filament , was obtained as well . the calculated results matched well the experimental results . taking advantage of the ultra - fast response characteristics of the devices , si - gaas pcss ' s are successfully applied to the broadening test of nanosecond laser pulses
应用单极电荷畴模型数值计算了lock - on效应的光、电时间延迟和载流子的渡西安理工大学硕士学位论文越速度（丝状电流穿越开关间隙的速度） ，所得计算结果与实验测试结果基本吻a利川半绝缘gaas光屯导开关的超快光l匕11向应灯性，成功地应川下纳秒激光脉冲展宽试验中，证明了开关可厂泛应川在超快光电响应和光电反馈网络中。 - In the picosecond and femtosecond time field , the durations of the pump and signal pulses are so short that special propagating characteristics of ultrashort pulse laser should be taken into account , especially the pulse broadening induced by the group velocity mismatch and the group velocity dispersion
在皮秒和飞秒时域，由于泵浦光与产生的信号光的持续时间特别短，故在讨论超短脉冲与物质相互作用时必须计及超短脉冲在介质中传输的特殊性质，尤其是群速失配与群速色散引起的脉冲展宽。
