Modeling the breather soliton dynamics in the mid-infrared Mamyshev oscillator
Abstract:
We have modeled a 2.8 μm mid-infrared Mamyshev oscillator and investigated the breather soliton dynamics in the oscillator numerically. The mid-infrared oscillator can support different breathers like frequency-unlocked breather solitons and subharmonic entrainment breathers exhibiting fractal dynamics. In addition, the Mamyshev oscillator can deliver the harmonic mode-locking with repetition rates up to ∼110 GHz via dissipative Faraday instability in the 2.8 μm spectrum window. By optimizing the gain saturation energy, a breather in the harmonic mode-locking regime has been identified in the Mamyshev oscillator. Our investigations can provide practical guidance for the experimental realization of mid-infrared Mamyshev oscillators and may offer perspectives on the nonlinear soliton dynamics supported by the mid-infrared Mamyshev oscillator.

RLC Circuit as a Damped Oscillator
Consider a series RLC circuit. Here, the presence of resistance in the circuit leads to energy loss due to joule heating in the resistance. Therefore, the total electromagnetic energy in the circuit is no longer constant and decreases with time. Since the magnitude of charge, current, and potential difference continuously decreases, their oscillations are said to be damped. This is...
