    • Abstract
  • We introduce the external-cavity semiconductor laser with feedback of Littrow configuration. The spectral line width is narrowed to be less than 1.2MHz and the output stability is remarkably enhanced. We also propose a new complex-cavity method which can greatly narrow the line width of a semiconductor laser.
