Ultra-slow dynamics of free-running ring lasers: towards a minimal model
Giovanni Giacomelli, Antonio Politi
The dynamics of a resonant, free-running ring laser, in the common case of a fast relaxation of the atomic polarization, is unexpectedly highly singular. As shown in [Phys. Rev. Re…
Nearly Hamiltonian dynamics of laser systems
Antonio Politi, Serhiy Yanchuk, Giovanni Giacomelli
The Arecchi-Bonifacio (or Maxwell-Bloch) model is the benchmark for the description of active optical media. However, in the presence of a fast relaxation of the atomic polarizatio…
Spaceless description of active optical media
Giovanni Giacomelli, Serhiy Yanchuk, Antonio Politi
The acclaimed Maxwell-Bloch (or Arecchi-Bonifacio) equations are a valid dynamical model, effectively describing wave propagation in nonlinear optical media: from the amplification…
The LANER: optical networks as complex lasers
Giovanni Giacomelli, Stefano Lepri, Cosimo Trono
We discuss the main features of a new optical system capable of laser action: the active complex optical network, or lasing network (LANER). The system is experimentally realized w…
Complex active optical networks as a new laser concept
Stefano Lepri, Cosimo Trono, Giovanni Giacomelli
Complex optical networks containing one or more gain sections are investigated and the evidence of lasing action is reported; the emission spectrum reflects the topological disorde…
Resonant activation in bistable semiconductor lasers
Stefano Lepri, Giovanni Giacomelli
We theoretically investigate the possibility of observing resonant activation in the hopping dynamics of two-mode semiconductor lasers. We present a series of simulations of a rate…
