Pump-Probe Spectroscopy — Revisited

  • P. R. Berman
Conference paper


A theory of pump probe spectroscopy is carried out using an amplitude approach in a bare state basis. The interplay between absorption and emission is clearly defined in this approach. Both closed and open systems are considered. The theory is applied to a calculation of the dispersion-like structure that appears when the probe frequency is nearly equal to the pump frequency, in the limit of large pump field detuning. The theory is extended to include a class of problems in which the recoil atoms undergo on the absorption or emission of radiation leads to resonance structures. The relationship of these recoil-induced resonances to the collective atomic recoil laser is discussed. The probe gain which occurs without level inversion in these systems cannot be viewed as a parametric process, in its normal sense.

    Haroche and Hartmann [S. Haroche and F. Hartmann, Phys. Rev. A 6 (1972) 1280] obtained the probe absorption spectrum in the context of velocity-tuned resonances in the theory of saturated absorption. They interpreted the structure centered near 5 = 0 as a competition between the two processes shown in Fig. 3 (a),(b) (which cancel exactly in our model). In the context of the relaxation model used in their paper, their amplitude interpretation does not appear to be justified.Google Scholar

    It is also possible to carry out the calculations using fields that are turned on adiabatically. The final steady state results are identical, but the contributions from individual diagrams differ for the two approaches.Google Scholar
