Raman lasing in As sub(2)S sub(3) high-Q whispering gallery mode resonators

We report the first observation of a nonlinear process in a chalcogenide microresonator. Raman scattering and stimulated Raman scattering leading to laser oscillation is observed in microspheres made of As sub(2)S sub(3). The coupled pump power threshold is as low as 13 mu W using a pump wavelength...
