Amplified spontaneous emission from ZnO nanostructures as scatterers in rhodamine 6G

Under high power, Nd: YAG 532nm, ns pulsed laser spectral narrowing of an amplified spontaneous emission (ASE) from ZnO nanostructures in rhodamine 6G has been studied. The dependence of emission intensity on excitation power, particle density of ZnO nanostructures, and silica as scatterers show a d...

Description
Summary:Under high power, Nd: YAG 532nm, ns pulsed laser spectral narrowing of an amplified spontaneous emission (ASE) from ZnO nanostructures in rhodamine 6G has been studied. The dependence of emission intensity on excitation power, particle density of ZnO nanostructures, and silica as scatterers show a distinct threshold. The Full width half maximum (FWHM) substantially reduces from 46 nm to 3.16 nm at high excitation power and ZnO-silica scatterer inclusion.
