Abstract

We present an ultra-compact passively Q-switched single-frequency fiber laser based on a home-made highly Er3+/Yb3+ co-doped phosphate fiber (EYDPF) and a semiconductor saturable absorber mirror (SESAM). An effective cavity length of less than 20 millimeters ensures a stably single-frequency operation of the Q-switched fiber laser. By employing a SESAM as the Q-switching, the narrowest pulse duration of sub-100 ns is realized, and the repetition rate of the Q-switched fiber laser reaches over 600 kHz. In addition, the achieved linear polarization extinction ratio is more than 25.0 dB.
