Abstract

All-fiber polarized passively mode-locked thulium-doped fiber laser system operating at 2 m region is presented. Inserting a semiconductor saturable absorber mirror (SESAM) in a Fabry-Perot (F-P) cavity, using master oscillator power amplifier (MOPA) configuration, the laser generated 15.24 ps pulses at repetition rate of 10.24 MHz, with high average power of 1.08 W. The spectrum bandwidth of the 2 m linearly polarized laser output was measured as 0.3 nm, and extinction ratio of the polarized pulses was 24.17 dB.
