Abstract

We compare the lasing threshold of random lasers composed of ielectric (alumina) or metal (gold) colloidal nanoparticles assessed by emission spectrum measurements. The lasing threshold can be observed when the emission intensity increases and emission linewidth decreases dramatically Random lasers with gold nanoparticles demonstrate higher intensity and lower lasing threshold than those with dielectric nanoparticles due to enhanced fields from localized surface plasmons.
