摘　　要：双条形激光器是一类重要的单片集成式激光器。以激光器速率方程为基础,采用数值分析的方法,研究双条形激光器的非线性动力学行为,讨论它在不同偏置、不同导引机制和初始相位差时的瞬态响应的特点,并指出不稳定性或混沌性是双条形激光器的本征工作状态。无论是无失谐的相位锁定还是相位稳定的双波长输出都经过器件结构的特殊设计,并在一定的工作条件下才能得到。The twin-stripe laser is an important type of monolithic lasers.Based on the rate equations,the nonlinear dynamic behaviors for the twin-stripe laser are analyzed by the numerical method.The transient responses are elaborately discussed for the twin-stripe laser with two kinds of different guidance mechanisms,and initial phase difference under different bias configurations.It is concluded that the instability/chaos is the intrinsic operation of the twin-stripe laser.Either phase-locked operation without detuning or stable output with two-wavelength only can be obtained under certain running conditions besides the special structure design.
