Limitations and improvements upon the two-level approximation for molecular nonlinear optics [PDF]

open access: yes, 2011
When parametric nonlinear processes are employed in the cause of efficient optical frequency conversion, the media involved are generally subjected to substantially off-resonant input radiation. As such, it is usually only electronic ground states of the
