title: Effect of the pumping geometry on the half-widths of the lasing peaks observed from Rhodamine 6G ethanol droplets.
abstract: The effect of the pumping intensity and geometry and the dye concentration on the lasing spectra from Rhodamine 6G ethanol droplets pumped with a high-power pulsed laser is investigated. The observed lasing peaks are found to broaden slowly whenthe pump intensity and dye concentration are increased. Significantly different spectra may be observed by pumping with a beam of diameter less than the droplet size.
