In this work, we demonstrate high-power mode-locked pulses in a double-clad erbium ytterbium-doped fiber laser (EYDFL) cavity using a saturable absorber with a structure of graded-index multimode fiber-step index multimode fiber-graded index multimode fiber (GIMF-SIMF-GIMF). Ultra-short pulses with a pulse duration of 2.32 ps and a repetition rate of 14.1 MHz with a center wavelength at 1543 nm were obtained. The measured signal-to-noise ratio was 54.5 dB. The highest average output power obtained was 322 mW when 8 W was pumped into the cavity. It has a pulse energy and peak power of 22.8 nJ and 9.84 kW respectively. The calculated peak power intensity was 15.4 GW/cm(2). This is the first report that demonstrated a GIMF-SIMF-GIMF-based SA in an EYDFL cavity in generating a high energy and peak power mode-locked fiber laser.
