Generating Short-Pulse Laser by Using a Quenched Distributed Feedback Dye Laser

The quenching effect of a distributed feedback dye laser is detail studied. In detail a simulation model of combined dye lasers relying on the rate equation system with both lasers having a common lasing medium is demonstrated. The calculation using this model for a dye material shows that single picosecond pulses are attained for a quenched distributed feedback laser (Q/DFDL) over a large lasing range of dye materials. The simulation results using pyrromethene 567 dye provided single pulses of 49 ps with high narrowband as could possibily be approached.
