Linewidth considerations in small signal gain or loss measurements with pulses
Description
This report discusses the difference between c.w. and pulse small signal gain or loss measurements. The spectrum of the gain or loss medium must be compared to the spectrum of the probe signal. First we discuss the formulation of the problem and apply the results to a Gaussian pulse propagating through a single line Lorentzian gain or loss medium. Second, we calculate the pulse energy gain or loss for the six overlapping lines of the iodine spectrum. (orig.)

Die vorliegende Arbeit diskutiert den Unterschied zwischen C.W.- und Kleinsignal-Plusverstaerkungs- oder Verlustmessungen. Das Spektrum des verstaerkenden oder daempfenden Mediums muss mit dem Spektrum des Mess-Signals verglichen werden. Zuerst wird die Formulierung des Problems dargestellt um anschliessend die Ergebnisse auf die Ausbreitung eines Gauss-foermigen Pulses in einem verstaerkenden oder daempfenden Medium mit Lorenenz-foermiger Einliniencharakteristik anzuwenden. Weiterhin wird die Energieverstaerkung oder -Daempfung des Pulses fuer den Fall der sechs ueberlappenden Linien des Iod-Spektrums berechnet. (orig.)
