Abstract
We show in our work that very narrow (FSR~0.09 nm) lasing modes can be formed from rhodamine 6G solution confined within quartz (SiO2) cuvette with suitable pumping scheme by Q switched Nd:YAG laser. With introduction of silver nanoparticles of different concentrations in rhodamine 6G we show that such lasing modes can be modulated as well as tuned in intensity, band spacing and emission wavelength. We also show that this system maintains a very high Q value > 6.4*1000 irrespective to change in other parameters.
