摘　　要：室温下半磁半导体Zn_(1-x)Mn_xSe(x=0.01)具有较宽的带边吸收.采用泵浦-探测系统观测到随激发功率增加吸收边的蓝移.在激发波长(532—560nm)范围内都能得到光学双稳现象.双稳开关时间短到800ps.讨论了双稳性的来源.Semimagnetic semiconductor Zn_(1-x)Mn_xSe (x= 0.01) exhibits a broad band absorption inthe region of band edge.The absorption is easily blue shifted with the pump-probe system.Theoptical bistability is obtained for the first time in a wider range of excitation wavelength.The origination of the nonlinear and bistable effects are discussed.
