This paper reports that the frequency responses of a direct-modulated DFB laser diode can be improved using an injection locking method.

验证了通过注入锁模方法，分布反馈(DFB)半导体激光器的频率响应可以得到明显的改善。

In this spectroscopy, both laser frequency and Zeeman effect of a sample are modulated, and then the signal with high signal to noise will be obtained by double demodulation.

它同时对激光频率和样品的塞曼效应进行调制，然后通过双解调来提取微弱的光谱信号。
