摘要

An ultra narrow linewidth fiber laser is presented,which is composed of a ring cavity laser and a linewidthnarrowing 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.
