Ultrafast dissipative soliton dynamics in isolator-free ring mode-locked laser

The presentation will cover investigation of a hybrid mode-locked Erbium-doped fibre ring laser without optical isolator. Creating different losses in the cavity for counter-propagating pulses via adjustment of net birefringence, the laser can operate in both unidirectional regimes with extinction over 22 dB, as well as can establish stable bidirectional generation. By using newly emerged high precision real-time measurement technologies of spatio-temporal intensity reconstruction and dispersive Fourier transformation, the ultrafast dynamics of solitons, including their formation, has been studied in bidirectional generation regime.
