Excitation spectra recorded for Cs vapor-Ar mixtures by monitoring the 852.1 nm relative laser pulse energy as the pump dye laser wavelength (lower abscissa) was tuned over the region. The Ar number density was fixed at and data were obtained for three temperatures [464 K (solid triangles: ▲), 475 K (open squares: ◻), and 485 K (solid circles: ●)] which correspond to , , and , respectively. The upper abscissa indicates the quantum efficiency of this laser for a given pump wavelength.
Dependence of the 852.1 nm laser pulse energy on the absorbed pump pulse energy for a dye laser excitation wavelength of 836.7 nm. Argon is again the sole rare gas and . The cell temperatures (and corresponding [Cs] values) are the same as those for Fig. 1.
Comparison of the excitation spectral data of Fig. 1 (solid triangles: ▲) with similar measurements in Cs–Ar–Kr (open circles: ○) mixtures for which (total rare gas pressure at 300 K of 500 Torr). The optical cell temperature for both sets of measurements was fixed at .
laser output pulse energy measurements: (a) Comparison of Cs–Ar and Cs–Ar–Kr mixtures for which the abscissa indicates the incident pulse energy ; (b) the same data as (a) but presented as a function of the absorbed pulse energy . The temperature was maintained at for all measurements, and the Ar and Kr number densities are both for the Cs–Ar–Kr experiments. In obtaining the Cs–Ar data, [Ar] was fixed at , and the dashed horizontal lines in (a) and (b) reflect the detection limit for the pyroelectric detectors.
