Non-Lorentzian Laser Bandshape Effects in Multiphoton Processes
In general, it is a complicated procedure to allow for the effects of non-Lorentzian lineshapes in atomic processes; in consequence, numerical methods often have to be employed. Recently, however, approximations leading to analytic solutions have been investigated. (See, for example, references 1 and 6. The papers cited here also contain references to work on Lorentzian line-shapes.) In this paper we continue the approach of Jackson and Swain2 where the non-Lorentzian effects are taken into account approximately by replacing the bare damping parameters, detunings and matrix elements of a monochromatic single-mode laser by corresponding quantities “dressed” by the laser fluctuations.
