WebJun 1, 1995 · The authors compare the effects of a coherent (periodic) modulation and of incoherent perturbations (noise). The model and the calculations are based on the theory of self-sustained, nonlinear oscillators. It is argued that these systems form an ideal basis for information-encoding processes in biological systems. Authors: Eichwald, C; Kaiser, F WebFeb 20, 2024 · The results of a computer simulation of laser beams focused by a combined multichannel array system in the atmosphere are presented. Beam propagation on atmospheric paths is considered taking into account the influence of turbulence and time-dependent thermal blooming interactions. The increase in the maximum intensity of the … how to replace signal light bulb

WebOct 23, 2012 · Under natural conditions, excitation of biological molecules, which display non-unitary open system dynamics, occurs via incoherent processes such as temperature changes or irradiation by sunlight/moonlight. The dynamics of such processes is explored analytically in a non-Markovian generic model. Specifically, a system S in equilibrium with … Webmodulation @9#, here the incoherent beam is spatially modu-lated directly by amplitude masks with various modulation periods. By actively seeding spatial noise onto an otherwise uniform incoherent beam, we demonstrate that the induced modulation instability has a maximum growth at a certain preferential perturbation period, leading to formation ... WebRandom perturbations will generally contain a broad range of frequency components, and so will cause the generation of spectral sidebands which reflect the underlying gain spectrum. ... Modulation instability of spatially and temporally incoherent light is possible owing to the non-instantaneous response of photoreactive systems, which ... how to replace silk browser
