  We report on a methodology for the evaluation of the DC characteristics,
small-signal frequency response and large-signal dynamic response of carrier
and photon density responses in semiconductor laser diodes. A single mode laser
is considered and described with a pair of rate equations containing a novel
non-linear gain compensation term depending on a single parameter that can be
chosen arbitrarily. This approach can be applied to any type of solid-state
laser as long as it is described by a set of rate equations.
