We demonstrate a hybridly mode-locked erbium-doped fiber laser. It combines saturable absorption and nonlinear polarization evolution to produce stable and purified femtosecond pulses with a high repetition rate of 212 MHz. The average output power is larger than 65 mW, and the single-pulse energy is 0.31 nJ at a pump power of 750 mW. A wide spectrum with FWHM of 61.4 nm is obtained. The dechirped pulse duration is 41.9 fs, which is near the transform-limited range.
