Title:
Universal Quasi-Level Parameter for the Characterization of Laser Operation 
Abstract:
Impact Statement: The classification of lasers in three- or four-level schemes is of fundamental importance for describing their operational characteristics. From solid state and fiber lasers, it is well known that the observed characteristics does not coincide with the number of physical levels, and typically even intermediate behavior is observed, which can be described by a continuous quasi-level parameter. Here we generalize the quasi-level concept so that it can be applied to a wide rang...    »
