【Abstract】 The bistabilities of the pumping laser and the emitting laser in an optically pumped sub-millimeter laser are studied by using a three-level homogeneously broadened two-field semiclassical model. The bistable behaviour varies drastically with the damping rates of the variables of the media. The emergence of bisability is governed by properly choosing the absorptive and gain coefficients of the media and the cavity damping coefficients.更多还原
