Abstract

Two lasing modes are observed for Sulforhodamine 640 in highly scattering media pumped by 3-ns 532-nm laser pulses. The stimulated-emission thresholds are found to depend on both concentration of laser dye and scattering particle density. At 2.5 × 10−2 M dye solution with TiO2 scattering nanoparticles from 5 × 109 cm−3 to 1011 cm−3, the thresholds are found to decrease by more than 2 orders of magnitude. The dominating lasing modes are found to switch from 650 to 620 nm with the increase of density of scatterers.
