A setup is described with which the spontaneous Raman scattering rate from pressurized gas samples is greatly enhanced inside a near-concentric optical cavity. The pump source is a high power multimode semiconductor laser diode that receives optical

We report the experimental investigation of a regime of microscopic Fabry-Perot resonators in which competing light-induced forces---photothermal expansion and photothermal refraction---acting oppositely and on different timescales lead to self-susta

A simple but highly effective method for enhancement of spontaneous Raman scattering from gases is described. It employs a multimode blue laser diode that receives feedback from a near-concentric bidirectional multipass cavity in such a way as to gen

Light recirculating inside an optical resonator can spontaneously trigger persistent cyclical thermomechanical mirror deformations. We have observed and characterized the dynamics of such deformations in high-finesse Fabry–Perot microcavities built

We have investigated the Purcell enhancement of spontaneous Raman scattering in microcavities with a test gas under pressure. Micromirrors were fabricated on bulk substrates and assembled into sealed microcavity arrays into which gases could be intro
