Classical lasing characteristics such as threshold behavior and stimulated emission, optical gain, emission linewidth narrowing and far-field modal pattern were observed at temperatures below 70 K under optical pumping.Submitted to Physical Review Letters (Nov.8th, 2004)Mesoscale and Nanoscale Physicstext
