To this aim, 1.5% Nd3+:Barium-Titanium-Silicate microspheres with diameters around 50 {\\mu}m were used as high quality factor (Q>10^6) whispering gallery mode lasing cavities. We have implemented a pump-and-probe technique in which the pump laser used to excite the Nd3+ ions is focused on a single microsphere with a microscope objective and a probe laser excites a specific optical mode with the evanescent field of a tapered fibre.","authors_text":"A.Toncelli, A.
