Physical Review A
The recent observations by Loy of amplitude modulation and compression of infrared laser pulses caused by passage through the dispersive modulator (a cell containing dilute NH3 vapor with a Stark-modulated resonant frequency) are explained. It is shown that there is a formal equivalence between (i) the passage of a near-resonant light beam through a vapor with a time-dependent resonant frequency, and (ii) the passage of a frequency-modulated light beam through a vapor with a constant resonant frequency. For low-intensity light this equivalence reduces the problem to the optical analog of chirp radar.
