Abstract

The theory of active-passive mode-locking in solid state lasers, controlled by a passive-negative feedback loop, is presented for the case of an intracavity two-photon absorbing semiconductor plate. It is shown that the combination of a GaAs plate and a pinhole acts simultaneously as power limiter and pulse compressor, ensuring optimum operation of the intracavity saturable absorber, making possible the generation of very long, flat, and stable trains of energetic, almost bandwidth limited pulses. The most recent experimental results are also presented, showing the excellent agreement with the numerical model.
