“…Previously, the cell was described in detail and could sufficiently maintain and vary the cell temperature and pressure [17,18]. The single end of a bifurcated fiber bundle was placed perpendicular to the beam to observe the side fluorescence of the cell and was coupled into a pair of Hamamatsu photomultiplier tubes (R5509).…”

The cross sections of spin-orbit energy exchange between the cesium 6 2 P 1/2 ↔ 6 2 P 3/2 states induced by collisions with N 2 , H 2 , HD, D 2 , CH 4 , C 2 H 6 , CF 4 , and C 2 F 6 were obtained for pressures less than 100 Torr at room temperature by means of steady-state laser-induced fluorescence techniques. The spin-orbit energy exchange rate with N 2 , H 2 , HD, D 2 , CH 4 , C 2 H 6 , CF 4 , and C 2 F 6 , have been measured as σ 21 (6 2 P 3/2 → 6 2 P 1/2 ) = 16. 3, 34.1, 30.0, 22.7, 21.4, 65.6, 64.8, and 137Å 2 and σ 12 (6 2 P 1/2 → 6 2 P 3/2 ) = 1. 8, 4.4, 4.1, 3.0, 2.9, 13.3, 9.7, and 16.3Å 2 , respectively. Correlations of the spin-orbit transfer probabilities with rotational-energy defect and vibrational-energy defect have been shown.

“…At 5 torr of N 2 and a cell temperature of 323 K, the D 1 transition is pressure broadened approximately 92 MHz and red shifted 39 MHz. [6][7] With natural broadening of 5 MHz, the homogeneous linewidth, excluding saturation is 97 MHz. The Doppler width at 323 K is significantly larger, 393 MHz.…”

Heat loads in Diode Pumped Alkali Lasers (DPAL) have been investigated using a diode laser to probe the radial dependence of the absorbance. A TiS pump laser heats the medium in a T=50-100˚C cesium heat pipe with 5 Torr nitrogen used for quenching. A tunable diode laser probes the spectral absorbance of the cesium cell. Local alkali concentration, temperature, and saturation broadening modify Voigt lineshapes in the wing of the hyperfine split lines. The temperature within the pumped volume exceeds the wall temperature by almost 200 C.

A mathematical method is described to compute the pressure dependent spectrum of the D 1 and D 2 lines of atomic cesium in the presence of argon. The method is based on the Anderson Tallman unified theory of pressure broadening in which the spectrum is determined form the Fourier transform of the auto-correlation function. The method uses modified potential energy surfaces of the ground and excited states that correlate to the 2 S 1/2 ground state and the 2 P 1/2 and 2 P 3/2 excited states at large inter-nuclear separation. These surfaces are used to form interaction difference potentials to determine the auto-correlation function. In addition to being able to compute pressure dependent spectra that exhibit asymmetry and far wing structure the method also allows us to compute the low pressure shift and broadening rates of the Lorentzian line core.
