Abstract

Summary form only. The amplitude stability of laser sources is of great interest to improve detection sensitivity in many applications as metrology, sensors, and optical communications. In this work we experimentally investigate the amplitude noise characteristics of the Tm:Ho laser system and we demonstrate reduction of the intensity noise and complete suppression of the relaxation oscillation peak of a diode-pumped single-frequency Tm-Ho:YAG laser. Intensity noise suppression is achieved by means of a suitable electronic feedback circuit acting on the drive current of the pump diode.
