GaAs/GaAlAs光双稳激光器稳态及动态特性的实验研究

本文报道了GaAs/GaAlAs侧向增益波导限制双稳激光器的静态及动态实验结果,对L—1特性,通态模式竞争、延迟特性、张弛振荡、有脉动、混沌现象等进行了研究,并对结果进行了讨论。实验表明,对于双区共腔双稳激光器,由于腔内可饱和吸收体的存在,使得其稳态及动态特性比普通均匀注入激光器复杂,与之有关的物理研究尚待进一步开展。

Experimental Investigation of Static and Dynamic Characteristics in a GaAs/GaAlAs Common Cavity Two Sections (CCTS) Bistable Laser

The static and dynamic characteristics of a GaAs/GaAlAs bistable laser with lateral gainwaveguide confinement, including L-I charateristics, mode competition during switching on,long delay, ultrafast light pulse, self-sustained pulsation, chaos etc., are reported and discussed.It shows that for a CCTS laser with a saturable absorbor in the cavity, the dynamic andstatic characteristics behave more complicated in comparison with that of a normal uniform injectionlaser, which demand a further analysis theoretically.
