Abstract

A single-mode Er/Yb-codoped short cavity fiber laser was experimented on the basis of previous short cavity fiber laser. The single-mode operation is realized by using the FBG and a 10cm section of Er/Yb co-doped fiber as a short cavity. The output power exceeds 1.5mW for pump power of 80mW. The linewidth of output laser was measured as 2MHz at 1532.64nm, and the side mode suppression ratio was 55dB. The single-mode was observed by an interferometer with free spectrum range (FSR) of 7.5GHz, and the longitudinal-mode fabric is analyzed. Relative intensity noise was less than -100dB/Hz.
