Abstract
Silver nanowires were used to enhance stimulated emission of Rhodamine 6G in a liquid random laser. Low-threshold coherent emission from the nanosecond-pulse-pumped random laser was achieved. Surface plasmonic resonance plays a key role in low-threshold operation of this random laser. The results demonstrate the ability of silver nanowires to enhance the stimulated emission, especially when the emission light from the dye molecules is far from the plasmonic resonance peak. Although the random laser shows different emission spectra in different directions, universal properties of strong interaction among multiple modes under different pump power densities were also demonstrated.
