For this, we first derive the electrical field in a strongly focused Gaussian light beam, and then consider the atomic response. Following the simple scattering model, the fraction of scattered optical power for a weak coherent probe field leads to unphysical scattering ratios above 1 in the strong focusing regime. A refined model considering interference between the exciting and scattered field into finitesized detectors or optical fibers is presented, and compared with experimental extinction measurements for various focusing strengths. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft. | Source Title: | New Journal of Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/53000 | ISSN: | 13672630 | DOI: | 10.1088/1367-2630/11/4/043011 |
