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

Measurements of boron isotopic ratios have been investigated using LIBS, and combined LIBS and Molecular laser-induced fluorescence (MLIF). Mixtures of various ratios of research grade H310BO3 and H311BO3 in pellet form were interrogated with a Q-swi

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
