Paper Abstract

External cavities terminated by a phase conjugate mirror have been used to provide a weak feedback to a synchronously pumped picosecond dye laser, a mode-locked argon ion laser and a continuous-wave argon ion laser. With the phase conjugate mirror, the external cavity is self-aligned and the reinjected field is best adapted to the intracavity field. Significant intensity noise reduction has been observed between 5 kHz and 1 GHz. For mode-locked lasers, it was possible to control the pulse length. These effects occur for wide ranges of cavity detuning and feedback level.
