Injection-locked flashlamp-pumped dye lasers of very narrow linewidth in the 570--720 nm range
Tunable and very narrow bandwidth flashlamp-pumped dye lasers are presented, in which spectral narrowing is achieved by injection locking of the pulsed lasers to the radiation of tunable single-mode cw dye lasers. We describe the electronic feedback stabilization of the amplifying ring cavity allowing a complete injection. Peak powers up to 10 kW at a bandwidth of 6 MHz were obtained over a 200-nm tuning range with three different dyes between 572 and 720 nm. The repetition rate is 10 Hz, limited by the dye circulating pumps. The emphasis of this work relates to the two following points: efficient injection locking over a broad frequency range, and special electronic design for accurate synchronization of several amplifying lasers. An example of application for high-resolution coherent anti-Stokes Raman spectroscopy is given.
