研究目的
Exploring single pulse regimes of ytterbium mode-locked fiber laser and relating them to the nonlinear amplitude modulation affecting the pulses inside the laser cavity.
研究成果
The internal nonlinear transmission curve of an Yb mode-locked fiber laser was measured, showing a clear experimental signature of the dynamical regime transitions where the slope suddenly varies as the regime changes. The evolution of the intracavity and extracavity average powers were different, due to the variation of the nonlinear polarization rotation as the pump power increases. However, the total power presents a linear behavior, demonstrating complementary character of intracavity and extracavity powers, which is a direct consequence of the energy conservation.
研究不足
The lack of resolution of the intracavity bifurcation diagram is due to the smaller difference between the intensities of the time series peaks.
