Abstract: We experimentally demonstrate a Mamyshev oscillator based on gain-managed nonlinearity and chirped pulse amplification. To the best of our knowledge, this configuration is first presented. Different from other Mamyshev oscillators, the gain-managed nonlinear regime serves as a seed provider instead of a power amplifier in one arm. The output pulse energy over 300nJ has been achieved from the chirped pulsed amplification in another arm. This configuration provided a new approach to design a high-energy ultrafast laser.
