Paper Abstract

Regenerative amplification of dark pulses in pulsed oscillators is described as injection seeding by a two-component signal: the first component is a carrier wave originating from a quasi-continuous single-mode laser; the second is a short pulse out of phase by ir. An iterative model predicts switching of the pulsed oscillator output from a train of dark pulses to a train of bright pulses as the resonance frequency of the seeded cavity is detuned from the frequency of the carrier wave. Experimental results obtained with a high-pressure CO2 laser system confirm the predictions.
