Parametric Model of a Laser with External Distributed Feedback in the System of Remote Measurement of Nanovibrations

Year: 2023

Type: conference-paper

Abstract: The paper studies the actual problem of building an adequate model of remote measurement of the characteristics of barely noticeable vibrations (nano vibrations) of the object of observation, which may be caused by some processes inside the object or external influences on it. Solving such problems is of key importance both for engineering sciences and for ensuring the safety of information technologies. The paper proposes a model that otherwise explains the interaction of individual feedback energy components in the formation of a useful signal. This reveals the reasons and makes it possible to determine the quantitative difference in estimates of the useful signal between the models: generally accepted and proposed. The proposed model, based on the photon lifetime and the equivalent length of the composite resonator, is in good agreement with the results of practical experiments and opens up new opportunities for improving the efficiency of the Laser Feedback Interferometry (LFI) model.
