Ion acoustic lower hybrid resonance
Web13 apr. 2024 · As a quantum mechanical process, FRET occurs between two fluorescent groups, where energy may transfer from a donor (D) to an acceptor (A) molecule, leading to a reduction in the donor’s fluorescence intensity and an increase in the acceptor’s fluorescence intensity, accompanied by a corresponding shortening and prolonging of … Web23 sep. 2024 · Lower hybrid wave is assumed to be pre-existed in the plasma. The physics of the process is as follows: a highly intense pump beam (X-mode) of frequency ω0 and wavenumber k → 0 propagates through the plasma. Being laser produced plasma, a self-generated magnetic field B → s exists in the plasma in the z-direction.
