Abstract
Abstract The interaction of an absorption line and a resonant laser is often modeled using a spectral overlap integral. Previous investigators have modified the traditional overlap integral to obtain a dimensionless overlap integral that affords a more practical interpretation. Unique to the derivation of the modified integral is the treatment of the laser-spectral-irradiance profile — its area is normalized to equal the spectral full-width at half-maximum. In this paper, the modified laser spectral irradiance is applied to obtain a dimensionless overlap integral for multi-photon absorption, including the case of two-photon absorption. Close attention is given t...
