Popis:	We present a narrow linewidth laser by optical feedback from a high-finesse F-P cavity. The cavity transmission feeds back to the laser diode by the external ring path. With a low servo bandwidth system, the feedback phase is compensated for maintaining the optical feedback operation. The linewidth of the optical feedback laser is reduced to 100 Hz, and the laser frequency noise in frequency range of 1 Hz to 10 kHz is suppression over 50 dB. It experimentally demonstrates the excellent characteristics of optical feedback technique.
