Power Exchange between Crossed Laser Beams and the Associated Frequency Cascade

چکیده
Consider the interaction of two crossed laser beams (A and B) that have a common carrier frequency ω0. The ponderomotive force associated with the beams drives an ion-acoustic (sound) wave (grating) of wave vector k k k s a b = − and frequency ωs = csks, as shown in Fig. 67.8(a). In turn, the grating scatters the laser light from one beam direction to the other. This interaction is governed by the equations3,6

Three-dimensional Analysis of the Power Transfer between Crossed Laser Beams
The power transfer between crossed laser beams made possible by an ion-acoustic (sound) wave (grating) has been studied theoretically2–5 and experimentally.6,7 Previously,4 we made a two-dimensional analysis of the power transfer between beams with top-hat intensity profiles in a homogeneous plasma. In this article we extend our previous analysis to include three dimensions and arbitrary intens...
متن کاملObservation of resonant energy transfer between identical-frequency laser beams*
Enhanced transmission of a low intensity laser beam is observed when crossed with an identical-frequency beam in a plasma with a flow velocity near the ion sound speed. The time history of the enhancement and the dependence on the flow velocity strongly suggest that this is due to energy transfer between the beams via a resonant ion wave with zero frequency in the laboratory frame. The maximum ...

In this paper, a new structure of HFTI-qZS-CMI has been proposed. The proposed structure is capable of generating high-voltage for medium to high power applications. By adding a switch, a capacitor and a high-frequency transformer and also eliminating an inductor from each qZS-CMI cell, the HFTI-qZS-CMI structure will be created. Using the high-frequency transformer in the proposed structure, l...

A new heterodyne nano-displacement with error reduction is presented. The main errors affecting the displacement accuracy of the nano-displacement measurement system including intermodulation distortion error, cross-talk error, cross-polarization error and phase detection error are calculated. In the designed system, a He-Ne laser having three-longitudinal-mode is considered as the stabiliz...
متن کاملA New Procedure for Determining Current Harmonic Contribution around an Operation Point at PCC Using Load Modelling Based on Crossed Frequency Admittance Matrix
Abstract:Today, one of the important issues of power quality (PQ) in power systems is the current harmonics. Increasing expansion of nonlinear loads at different parts of the electric network makes harmonic distortion flow through the network. This causes the network to have background voltage and current harmonic distortion and even affect on the PQ of linear load performance. Therefore, it is...
