We analyze the dynamical instabilities of an additive-pulse–modelocked Nd:YAG laser; period doubling up to period 8, quasi-periodicity and high-dimensional chaos are observed. Experimental and numerical data are analyzed using bifurcation diagrams, spectrograms, and Grassberger-Procaccia analysis. It is shown that the instability threshold is not affected if the fiber resonator length is chosen as an integer multiple of that of the main resonator, as is often done. However, the dynamics beyond the bifurcation depends on the length ratio in a systematic manner.
