Cascaded Raman lasing in packaged high quality As₂S₃ microspheres.
We report the observation of cascaded Raman lasing in high-Q As₂S₃microspheres. Cascaded stimulated Raman scattering emission is obtained up to the 5th order for a pump wavelength of 1557 nm and up to the 3rd order for a pump wavelength of 1880 nm. High-Q As₂S₃microspheres are used in a self-frequency locking laser setup without an external laser source. Threshold curves measurements are presented and follow the expected coupled mode theory behavior with a sub-mW threshold pump power.
