摘要

We report on the investigation of intermode beating mode-locking (IBML) pulse generation in a simple all fiber Tm3+-doped double clad fiber laser (TDFL). This IBML TDFL is implemented by matching longitudinal-mode frequency between 793 nm laser and TDFL without extra mode-locker. The central wavelength of ~1983 nm, the fundamental pulse frequency of ~9.6 MHz, and the signal to noise ratio (SNR) of >50 dB is achieved in this IBML TDFL. With laser cavity optimization, the IBML TDFL can finally generate an average output power of 1.03 W with corresponding pulse energy of ~107 nJ. These results can provide an easily accessible way to develop compact large energy, high power TDFLs.
