摘要：

With the use of an optical frequency discriminator and negative electrical feedback, wide-bandwidth frequency noise suppression with simultaneous FM equalization of a semiconductor laser is achieved. With a heterodyne optical phase-lock loop the intermediate-frequency linewidth of two lasers, each using negative electrical feedback, was reduced from more than 25 MHz to less than 0.01 Hz.
