Abstract
Investigation of the stability of pulse repetition rate emitted with semiconductor lasers in the regime of passive mode locking has been conducted. It was shown experimentally that the decrease of an overlap integral of the quantum-sized active layer with the waveguide mode and the increase of the time of the carrier capture on the emitting level resulted in narrowing of the radio-frequency linewidth.
