Investigation of Intensity Noise in a Diode-Pumped Tm-Ho:YAG Laser

Abstract

Laser intensity stability is of great interest for system design in metrology, sensor applications [1], and optical communications [2] to improve detection sensitivity and overall system performance. In this work we focus our attention on and experimentally investigate the physical mechanisms through which external noise sources induce intensity noise in a singlefrequency Tm-Ho:YAG laser to be used as local oscillator for 2-µm coherent LIDAR applications.
