报道了利用１．３μｍ分布反馈（ＤＦＢ）半导体激光器注入锁定普通半导体激光器后的模式及其远场分布特性实验。在不加隔离器和主被动激光器偏振方向相互垂直的情况下，获得了静态和动态单纵模运转，并观察和测量了普通半导体激光器注入锁定前后输出光的远场分布，最后对实验结果进行了讨论。
The mode and the far-field distribution characteristics experiment of a conventional semiconductor laser using a 1.3μm distributed feedback (DFB) semiconductor laser are reported. The static and dynamic single-longitudinal mode operation was obtained without polarizations of the isolator and the active and passive lasers, and the far-field distribution of the output light before and after the normal semiconductor laser was injected was observed and measured. Finally, the experimental results were carried out Discuss.
