Laser action has been demonstrated in chalcogenide glass microsphere. A sub millimeter neodymium-doped gallium lanthanum sulphide glass sphere was pumped at 808 nm with a laser diode and single and multimode laser action demonstrated at wavelengths between 1075 and 1086 nm. The gallium lanthanum sulphide family of glass offer higher thermal stability compared to other chalcogenide glasses, and this, along with an optimized Q-factor for the microcavity allowed laser action to be achieved. When varying the pump power, changes in the output spectrum suggest nonlinear and/or thermal effects have a strong effect on laser action.
硫族化物玻璃微球已实现激光作用。一个亚毫米级的掺钕镓镧硫化物玻璃球由一个激光二极管在808纳米波长下泵浦，并在1075至1086纳米波长之间实现了单模和多模激光作用。与其他硫族化物玻璃相比，镓镧硫化物玻璃具有更高的热稳定性，再加上微腔的优化品质因数，使得实现激光作用成为可能。当改变泵浦功率时，输出光谱的变化表明非线性和/或热效应会对激光作用产生强烈影响。
