Pulse Broadening

A signal optical pulse propagating in the fiber is affected by many factors, one of the most important among them is dispersion. Under the dispersive influence, the optical pulse is reshaped, particulally, its duration is changed. Especially, the pulse duration change of the optical short pulse with the frequency-chirp is unregular. It influences to the propagating distance in the fiber optic network.In this paper, the expression of the signal optical pulse with the frequency-chirp propagated through the dispersive fiber is derived. This expression described the broadening of the pulse in propagating process (broadening factor), which depends on the frequence chirp and dispersive parameters. The influence of those parameters on the pulse broadening is simulated and discussed.

AbstractThe dual laser-produced plasma technique for the study of ionic absorption spectra has been developed by the use of two Q-switched ruby lasers to enable independent generation of the absorbing and back-lighting plasmas. Optical pulse handling is used in the coupling cicuits to enable reproducible pulse delays from 250 nsec. to 10 msec, to be achieved. At delay times > 700 nsec. spectra of essentially pure neutral species are observed. The technique is valuable, not only for obtaining the neutral spectra of highly refractory and/or corrosive materials but also for studying behaviour of ionic species as a function of time. Typical spectra are shown in Fig. 1.
