Abstract

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 nm to 597 nm . It was also tuned back to 648 nm again by reducing the voltage back to 0 V .
