“…Most of the work done in nonlinear dynamics for Yb is theoretical [16,17,18,19,20], and some experimental work present different types of phenomena such as rogue waves [21,22], noise-like pulse formation [23,24,25], soliton explosion [26] and soliton molecule formation [2]. As pointed out by references [16,27], YDMLFL constitutes a rich nonlinear system, used in several different applications. This leads us to conclude of the importance of a proper experimental characterization of unusual operating regimes.…”

We experimentally study the nonlinear dynamics of a femtosecond ytterbium doped mode-locked fiber laser. With the laser operating in the pulsed regime a route to chaos is presented, starting from stable mode-locking, period two, period four, chaos and period three regimes. Return maps and bifurcation diagrams were extracted from time series for each regime. The analysis of the time series with the laser operating in the quasi mode-locked regime presents deterministic chaos described by an unidimensional Rössler map. A positive Lyapunov exponent λ = 0.14 confirms the deterministic chaos of the system. We suggest an explanation about the observed map by relating gain saturation and intra-cavity loss.
