Single-mode flashlamp-pumped dye laser oscillators.
In this paper, we report single-longitudinal-mode operation in a flashlamp-pumped dye laser incorporating a multiple-prism beam expander with the grating either in a Littrow or grazing-incidence configuration. Linewidths in the 260-MHz range were obtained, using rhodamine 590 dye at output energies exceeding 60 mJ. Pulse duration for the multiple-prism Littrow dye laser oscillator was approximately 200 ns (FWHM).
