- They pointed out that modulation wave fronts ( such as those in the front of a light pulse ) in a negative index material are aligned the same way as they are in a positive index material ? anything else would violate basic causality and require parts of the wave to travel with infinite velocity
他们指出在负折射率材料中调制波前（例如光脉冲前端的波前）的方向，与在正折射率材料中相同；若非如此，就会违反基本因果律，且部份波的前进速度将成为无限大。 - Recent progress in ultrafast optics has allowed the generation of ulfcraintense light pulses comprising merely a few field oscillation cycles . the arising intensity gradient allows electrons to survive in their bound atomic state up to external field strengths many times higher than the binding coulomb field and gives rise to ion - ization rates comparable to the light frequency resulting in a significant extension of the frontiers of nonlinear optics and ( nonrelativistic ) high field physics
随着超快光学技术的发展，仅含几个振荡周期的超强脉冲已经能产生，且其强度梯度可使电子存在比库仑束缚场高许多倍的外场产生的原子束缚态上，并产生了同光频相差不大的电离率，从而促进了非线性光学前沿及非相对论的强场物理的延伸。 - 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。 - The transmitter transfers three lines of signal including one line of audio signal , one line of video signal and one line of data signal which are pretreated singly at first , then processed by the way of the fdm , the pfm modulation , the driving laser source and finally transformed the light pulse and feeded in the fiber to be transmitted
Pfm光发射机传输了一路音频、一路视频以及一路数据信号，三路信号各自先进行预处理后再频分复用， pfm调制，驱动光源，转换成光脉冲，馈入光纤进行传输。 - From three - wave coupling equations , the optimal crystal length , conversion efficiency and parametric light pulse width are computed numerically when clbo is used in picosecond optical parametric amplification . the results present that clbo are suited for optical parametric amplification in short wave band . in order to get higher conversion efficiency , the crystal length should be optimized according to the intensities of pump and signal waves
从三波耦合方程出发，对clbo用于皮秒级光参量放大时，最佳晶体长度、转换效率和参量光的脉冲宽度进行了理论分析和数值模拟，结果表明clbo晶体适合在短波范围作光参量放大，为达到高的转换效率和窄脉宽的信号光输出，泵浦光和初始入射信号光的强度应根据晶体长度取最优化值。
