摘要：

Here we report electric-field-induced, wavelength-tunable random lasing action in a liquid-crystal infiltrated disordered planar microcavity. With the increasing of external voltage from 0 V to 30 V, the emission wavelength of the random laser was continuously tuned from 648 run to 597 nm. It was also tuned back to 648 nm again by reducing the voltage back to 0 V. (C) 2009 Optical Society of America
