摘要：

We demonstrate a stable mode-locked Erbium-doped fiber laser (EDFL) by employing a titanium dioxide (TiO2) polymer composite film as a passive SA. The film has a loss of 3.0 dB and modulation depth of 40.0% at 1550 nm. A 186 m long single-mode fiber (SMF) is added into the laser cavity so that it operates in normal dispersion regime. The ring laser produces a stable dissipative solition mode-locking pulse as the input pump power is maintained within 73 mW to the maximum power of 157 mW. The laser has a central wavelength, 3 dB spectral bandwidth, pulse duration, and repetition rate of 1563 nm, 0.39 nm, 271.3 ns, and 1.038 MHz, respectively. The maximum pulse energy of 6.25 nJ is obtained at the maximum input pump power of 157 mW. This result suggests that TiO2 could be further investigated for pulsed laser applications.
