ultrashort pulses

Observation of bifurcations in the nd-­glass laser with short-­time resonant modulation of loss

The condition of a bifurcation of a round-trip time of ultrashort pulses (USP) in the Nd-laser with short-time resonant modulation of loss is found out experimentally. This condition is exhibited in the period doubling in the area of a small detunings of the modulation frequency and an intermodal interval. It is revealed, that the pumping level (amplification in the active medium) is a major factor, influencing this effect.
