摘要

We propose and demonstrate a synchronously pumped mode-locked Tm-doped fiber (TDF) laser without any extra mode-locking elements.Pumped by a 1.56μm pulse fiber laser,the TDF laser generates 1.17ps pulses with a spectral width of 9.7nm and a repetition rate of 9.33MHz.The emission wavelength is tunable along with the cavity length detuning in a wide range of 3mm.The high detuning toleration is beneficial to achieve high temperature and vibration stability in all-fiber configuration lasers.
