Abstract: Theoretical studies of the semiclassical laser equations for two-level atoms predict the appearence of a delayed bifurcation when the pump parameter is swept linearly in time across the threshold region1. Recently, such a delayed bifurcation has been observed by Scharpf et al2. (2) at the threshold of an Ar+ laser by varying the cavity losses.
