“…Hence the early published articles [1,2] concerned the data of these processes without chirping of the incident laser pulse it is interesting to elucidate the chirping influence on the transformation of an outcoming pulse. The brief results of the experiments combined with the computer simulation are presented below.…”

Abstract. It is known that ultrashort pulse coherent propagation through the resonant absorbing medium leads to the pulse splitting and pulse train generation. First of these pulses is the input pulse and the following pulses are resonant medium response. It is also known that such a propagation mode leads to the «spectrum condensation» effect, at which broad-band input femtosecond laser emission, as it leaves opically-dense medium, centralized in the vicinity of the resonance absorption lines. It's interesting to clear up the dependence of a condensation effect on an input femtosecond pulse phase modulation value (chirp).

“…But from some threshold value N 0 , the emission spectrum of the atomic ensemble splits into 2 satellites [2]. Their frequency slitting value is defined by the value of the polariton mode frequency splitting value in the resonant medium and increases as N 0 increases.…”
