【摘要】 本文从Ｍａｘｗｅｌ－Ｂｌｏｃｈ方程出发，分析了均匀加宽二能级原子系统环形激光器中的吸收光学双稳态，计算了出现不稳定性区域，并通过数值计算给出了混沌过程和吸引子更多还原

【Abstract】 In this ppaper, from the Maxwell Bloch equation, we analyse absorption optical bistability in a ring laser of which contain uniform broadening two level atoms, calculate the region of which appear unstability, and give the chaotic process and the attractor.更多还原
