Self-similarities in the frequency-amplitude space of a loss-modulated CO2 laser.

چکیده
We show the standard two-level continuous-time model of loss-modulated CO2 lasers to display the same regular network of self-similar stability islands known so far to be typically present only in discrete-time models based on mappings. Our results suggest that the two-parameter space of class B laser models and that of a certain class of discrete mappings could be isomorphic.

Lasers with modulated parameters are arguably among the simplest and most accessible laser systems of interest for applications in science and engineering and for theoretical investigations. The intrinsic interest in practical applications and in the nonlinear dynamics of modulated lasers has spurred a wide range of studies after the remarkably influential work of Arecchi et al. [1] reporting t...
متن کاملExperimental observation of parametric effects near period doubling in a loss-modulated CO2 laser.
A number of parametric effects, such as suppression of period doubling, shift of the bifurcation point, scaling law relating the shift and the perturbation amplitude, influence of the detuning on the suppression, reaching of the maximum gain between the original and shifted bifurcation points, and scaling law for idler power are experimentally observed near period doubling bifurcation in a loss...
متن کاملQuadrature Amplitude Modulated Digital Radio Transmission Modeling and Simulation
Computer aided design and computer aided modeling tools are becoming increasingly important in the design and performance evaluation of communication systems. In this work, we report on the computer simulation modeling study of terrestrial digital microwave radio transmission, using Block Oriented System Simulator package (BOSS). The work concentrates on semi-analytical error rate evaluation in...
متن کاملControlling Multistability by Small Periodic Perturbation
A small perturbation of any system parameters may not in general create any significant qualitative change in dynamics of a multistable system. However, a slow-periodic modulation with properly adjusted amplitude and frequency can do so. In particular, it can control the number of coexisting attractors. The basic idea in this controlling mechanism is to introduce a collision between an attracto...
متن کاملInvestigation of a CO2 laser response to loss perturbation near period doubling.
Small signal amplification and deamplification phenomena near the onset of a period-doubling bifurcation (PDB) have attracted much attention recently because of their possible applications for signal amplification, in particular to increase sensitivity in modulation intracavity spectroscopy [1] and because of their relationship with the phenomenon of "squeezed light" in quantum optics [2]. The ...
