Mamyshev oscillator based on gain-managed nonlinearity and chirped pulse amplification
arXiv:2512.02199
Abstract
We experimentally demonstrate a Mamyshev oscillator based on gain-managed nonlinearity and chirped pulse amplification. Different from other Mamyshev oscillators, the gain-managed nonlinear regime serves as a seed provider instead of a power amplifier in one arm of this laser. The output pulse energy over 300 nJ and pulse width of 739 fs has been achieved from the chirped pulsed amplification in another arm. This configuration provided a new approach to design a high-energy ultrafast laser.
