负色散 meaning in Chinese
negative dispersion
Examples
- However , the dispersion - absorption relations of the media can be dramatically modified by employing coherent fields to drive it
在中心光谱处的负色散行为也会因吸收而被破坏。 - 5 . without making the paraxial approximation , a detailed study on the propagation of ultrashort pulsed bessel beams in linear normal and anomalous dispersive media has been performed using the method of fourier transform
未作近轴近似的条件下，用傅立叶积分变换法详细研究了超短脉冲贝塞尔光束在正、负色散介质中的传输特性。 - Second , negative dispersion without absorption , which leads to superluminal light propagation , is achievable in the central resonance structure of the dispersion spectrum . the negative dispersion is slightly weakened as the spacings between dressed states increase
其次，在色散光谱的中心区域，呈现出无吸收负色散，这种效应能够导致超光速传播，但它随着修饰态间距增加而减弱。 - The equation is also a unified approach to the design of common trible - clad optical fibers . by genetic algorithm , the optimized refractive index profile ( rip ) of dcf is calculated to obtain maximal value of negative dispersion . this rip ensures the propagation of basic mode in dcfs
然后根据色散方程(特征方程) ，用基因法优化色散补偿光纤的负色散，得到了求得最大负色散时的色散补偿光纤的光纤结构，同时保证基模在光纤中的传输。 - The pulses can be broadening and become negatively chirped while propagating in anomalous dispersive media . in normal dispersive media , the pulses can be broadening , positively or negatively chirped , or even the dispersion - free propagation can be achieved , if the beam and material parameters are suitably chosen
在负色散介质中传输时，脉冲会变宽、带有负惆啾:而在正色散介质中传输时，脉冲会变宽、带有正惆啾或负叨嗽，当光束和色散参数满足一定条件时能实现“无衍射无色散”传输。
