We have observed period doubling and quasi-periodicity in an additive-pulse mode-locked F-center laser. Experiments show that period doubling is often present even though standard diagnostics such as pulse autocorrelations and spectra give no indication of it. Numerical simulations show that the period doubling is associated with strong pulse reshaping.
