Abstract :
This paper presents the characteristics of energy transfer distributed feedback dye laser (ETDFDL) in a mixture of Rhodamine B (RB) and of cresyl violet (CV) dyes pumped by 532 nm Nd:YAG laser both theoretically and experimentally. The characteristics of donor DFDL, the acceptor DFDL, the dependence of their pulse widths and output powers on donor-acceptor concentrations and pump power are studied. Experimentally the output energy of DFDL is measured at the emission peaks of donor and acceptor dyes for different pump powers, donor-acceptor concentrations and continuous tunability is observed from 565 nm to 685 nm using prism dye cell arrangement.
