文摘We demonstrate stable single-mode CW operation of a DFB ring laser based on Er3＋ doped photonics crystal fiber （PCF）. The incorporation of a ring cavity allows one single mode to lase and also suppresses the unwanted effect of self-pulsing. Such a narrow linewidth source in PCF has great potential in spectroscopy.
