摘　　要：本文用三能级均匀加宽的双光场激光半经典方程,研究了光泵亚毫米波激光器的泵浦场和发射场的光学双稳特性.双稳行为受选择介质的弛豫速率参数的变化影响较大.泵浦光的吸收系数,发射光的增益系数和腔损耗系数的大小也直接影响到双稳能否出现.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.
