Flashlamp pumped narrow-linewidth dispersive dye laser oscillators: very low amplified spontaneous emission levels and reduction of linewidth instabilities.
We report on optimized narrow linewidth (138-MHz </= Deltanu </= 360-MHz) flashlamp excited dispersive dye laser oscillators yielding extremely low amplified spontaneous emission levels in the 10(-10) range. In addition, we specify thermal and dye flow conditions where linewidth instabilities, for double-longitudinal-mode oscillation, can be neutralized.
