Abstract

Rubidium vapor was used to characterize the output of a tunable, pulsed alexandrite laser operating at 780 nm. Rubidium spectra were obtained at temperatures of 23, 50, 110, and 140°C. Excellent agreement was obtained with computer-synthesized spectra in which laser linewidth was the only free parameter. Each of the twelve hyperfine structure components of the rubidium 52P3/2 52S1/2 transition was represented by a Voigt profile while a Gaussian profile was assumed for the laser pulses. Optimum calculated values for the laser linewidth at a pumping energy 40% above threshold were 0.065 cm-1 and 0.035 cm-1 for the Q-switched pulse and for the free-running train of pulses, respectively. The laser output was found to be spectrally compact with no evidence of energy outside the narrow central feature.
