Measuring Linewidth Enhancement Factor by Relaxation Oscillation Frequency in a Laser with Optical Feedback [PDF]
Sensors, 2018 This paper presents a new method for measuring the linewidth enhancement factor (alpha factor) by the relaxation oscillation (RO) frequency of a laser with external optical feedback (EOF).

Features of a Self-Mixing Laser Diode Operating Near Relaxation Oscillation [PDF]
Sensors, 2016 When a fraction of the light reflected by an external cavity re-enters the laser cavity, both the amplitude and the frequency of the lasing field can be modulated. This phenomenon is called the self-mixing effect (SME).

Mathematical Biosciences and Engineering, 2023 In this paper, we consider the dynamics of a slow-fast Bazykin's model with piecewise-smooth Holling type Ⅰ functional response. We show that the model has Saddle-node bifurcation and Boundary equilibrium bifurcation.

Two-stroke relaxation oscillators [PDF]
Nonlinearity, 2020 Two-stroke relaxation oscillations consist of two distinct phases per cycle - one slow and one fast - which distinguishes them from the well-known van der Pol-type 'four-stroke' relaxation oscillations. This type of oscillation can be found in singular perturbation problems in non-standard form, where the slow-fast timescale splitting is not ...

Frictional behavior of quartz gouge during slide-hold-slide considering normal stress oscillation
International Journal of Coal Science & Technology, 2023 Slide-hold-slide (SHS) test is an essential experimental approach for studying the frictional stability of faults. The origin SHS framework was established based on a consistent constant normal stress, which cannot truly reflect the stress disturbance ...

Dynamics in diffusive Leslie–Gower prey–predator model with weak diffusion
Nonlinear Analysis, 2022 This paper is concerned with the diffusive Leslie–Gower prey–predator model with weak diffusion. Assuming that the diffusion rates of prey and predator are sufficiently small and the natural growth rate of prey is much greater than that of predators ...
