Zinc Oxide Random Lasers: Controlling the Emission Properties
Presented to Tektronix Advanced Metrology Group (Oct 25, 2017)
Random lasers are unique optical systems where high-Q laser modes are formed via resonant scattering in a gain medium, leading to a variety of lasing phenomena that are facilitated by the random structure of these systems. In this presentation, experimental and theoretical results are presented to illustrate how systems designers can exert some control over the emission characteristics of random lasers. Such methods for control include pulse shaping, embedded high-Q structures in random gain media, and addition of lossless scatterers to maximize net gain in the system.
