Paper Abstract

We report on the laser characteristics of solid-state dye lasers pumped directly by a pulsed red diode laser. A 1.6-mm thick disk of Oxazine 725 in modified PMMA was excited longitudinally in a nearly hemispherical resonator at ≅671 nm. We operated at rep rates up to 1 kHz, with only a modest drop in energy per pulse at the highest rep rates. (The energy at 1 kHz is ≅83% of that measured at 1 Hz.) The spectral output of this solid-state dye laser was centered at ≅740 nm with a bandwidth (FWHM) of ≅10.5 nm. For a pump pulse of 230 ns (FWHM), the dye laser output was ≅155 ns in duration, and tracked the pump pulse well after turn on. The maximum observed efficiency for a sample containing Ox 725 in modified PMMA was 18%. Data on other solid dye media are also presented.
