双模含失谐均匀加宽激光的不稳定性与混沌

研究了双模含失谐均匀加宽激光的不稳定与混沌行为，在不同失谐情况下给出了激光经Ｈｏｐｆ分岔而出现洛仑茨不稳定的判据，它与模式跳变不稳定共同构成了激光的不稳定边界，并且模拟发现洛仑茨不稳定在一定条件下将触发激光模式的跳变，从而表现出双模所特有的非稳定现象。

Unstability and Chaos of a Detuned Two-Mode Homogeneously Broadened Laser

Unstubility and chaos of a detuned homogeneously broadened laser are studied.Under the different conditions, the criterions, when a laser becomes unstable via a Hopf bifurcation and mode hopping, are given, which defines the unstability margin of a laser. Moreover, by numerical simulation, we verify the criterions and find that Lorenz unstability can trigger mode hopping unstubility on certain condition.
