An ultra narrow linewidth fiber laser is presented, which is composed of a ring cavity laser and a linewidth-narrowing module. The fiber laser is introduced in detail and the single mode operation of the laser is verified. Using a revised self-heterodyne detection method, experimental data of the laser linewidth against the pump power are presented. The narrowest linewidth is measured to be 109 Hz, whereas the output power is 1.1 mW.
