Abstract
Summary form only given. Laser source amplitude stability is of great interest to improve detection sensitivity in many applications such as metrology, sensor, and optical communications. We experimentally investigate, for the first time to our knowledge, the noise characteristics of a diode-pumped single-frequency Tm,Ho:YAG laser and we report complete suppression of the relative-intensity noise (RIN) peak by means of a suitable electronic feedback circuit acting on the drive current of the pump diode.
