A laser spectroscopy system with combined absorption, polarization rotation and fluorescence detection to study two photon transitions in atomic rubidium

O López-Hernández, Santiago Hernández-Gómez, F. Ponciano-Ojeda +6 more

The design and construction of an experimental system for studying two photon spectroscopy processes in atomic rubidium is presented. It is designed to measure absorption and polarization rotation induced by any of the two laser beams and also the visible fluorescence that results from decay of the excited states. Two home-built diode lasers are used to produce the optical fields that later interact with room temperature rubidium atoms. Using counterpropagating beams allows velocity selection of the groups of atoms that interact with both laser beams. The system was tested in the 5 S?5 P3/2 ?5 Dj ladder energy level configuration of atomic rubidium. Blue fluorescence (420 nm) that results from decay of the intermediate 6Pj states is filtered and then measured with a photomultiplier tube. Absorption and fluorescence spectra provide mutually complementary information about the interaction between the rubidium atoms and the two optical fields.

Probe-intensity dependence of velocity-selective polarization spectra at the rubidium D2 manifold and comparison with a rate-equation calculation

J. Flores-Mijangos, F. Ramírez-Martínez, Ricardo Colín‐Rodríguez +2 more

We present a detailed study of the effect of a strong and circularly polarized coupling beam on a probe beam locked to a hyperfine transition of the rubidium ${D}_{2}$ manifold. Experiments were carried out in the co- and counterpropagating configurations. Counterpropagating beams are used to study the effect of the probe beam intensity on absorption and polarization spectra. These data are compared with results of a rate-equation calculation. The absorption spectra show very clear indication of saturation, with different saturation intensities for each atomic line. The slope of the dispersionlike profile of the polarization signal increases with the intensity of the probe beam. These results are in very good agreement with the calculation. Experimental absorption and polarization spectra in the copropagating configuration are also well reproduced by the rate-equation calculation. The dispersion profiles in the polarization signal can be used to lock the coupling laser frequency at well defined frequencies.

Velocity selective bipolarization spectroscopy for laser cooling of metastable krypton atoms

Y. B. Kale, Vibhuti Bhushan Tiwari, Sunita Singh +2 more

We report a velocity selective bipolarization spectroscopy (VS-BPS) technique to generate a background-free, dispersion-like reference signal which is tunable over a wide range of frequency. In this technique, a pair of linearly polarized weak probe beams passing through a gas cell of metastable krypton (Kr*) atoms overlaps with a pair of counterpropagating circularly polarized strong pump beams derived from an independently tunable control laser. The polarization spectroscopy signals from the two probe beams, after subtraction, result in the VS-BPS signal. The spectral shifting in the VS-BPS signal can be achieved by tuning the frequency of the control laser. The dependence of the amplitude and slope of the VS-BPS signal on the RF power used for excitation of Kr atoms in the gas cell and on the power of pump beams has been studied. The frequency stability of a diode laser locked with VS-BPS signal has been found to be better than the frequency stability of the laser locked with a saturated absorption spectroscopy signal. The VS-BPS signal is finally used for stabilization and tuning of the cooling laser frequency for a magneto-optical trap for Kr* atoms.
