Time-dependent field equations for paraxial relativistic electron beams: Beam Research Program (open access)

Time-dependent field equations for paraxial relativistic electron beams: Beam Research Program

A simplified set of field equations for a paraxial relativistic electron beam is presented. These equations for the beam electrostatic potential phi and pinch potential Phi identical to A/sub z/ - phi retain previously neglected time-dependent terms and for axisymmetric beams reduce exactly to Maxwell's equations.

Steady-state approximations in Raman excitation equations (open access)

Steady-state approximations in Raman excitation equations

This memo presents equations describing propagation of beams of nearly monochromatic radiation through a Raman-active molecular vapor, under conditions of steady excitation of quantum-mechanical molecules by classical radiation (that is, by radiation that comprises a large number of photons per mode). Such conditions apply in the continuous-wave experiments that are conducted to measure such properties as Raman gain or Raman scattering cross sections. Under those circumstances the propagation is described by rate equations for molecular excitation and rate equations for photon numbers. Although these conditions do not apply for short-pulse transient excitation, both types of processes are parameterized by the same molecular polarizability matrix elements. This memo discusses those parameters, as extracted from steady state observations.

2, Pulse-mode expansions and refractive indices in plane-wave propagation (open access)

2, Pulse-mode expansions and refractive indices in plane-wave propagation

This memo presents basic background theory for treating simultaneous propagation of electromagnetic pulses of various colors, directed along a common ray, through a molecular vapor. The memo discusses some techniques for expanding the positive frequency part of the transverse electric field into pulse modes, characterized by carrier frequencies within a modulated envelope. We discuss, in the approximation of plane waves with slowly varying envelopes, a set of uncoupled envelope equations in which a polarization mode-envelope acts as a source for an electric-field envelope. These equations, when taken with a prescription for the polarization field, are the basic equations of plane-wave pulse propagation through a molecular medium. We discuss two ways of treating dispersive media, one based upon expansions in the frequency domain and the other based in the time domain. In both cases we find envelope equations that involve group velocities. This memo represents a portion of a more extensive treatment of propagation to be presented separately. Many of the equations presented here have been described in various books and articles. They are collected and described here as a summary and review of contemporary theory.
