摘要:
We report the homodyne detection of phase modulation sidebands induced on a laser beam by a coherently bunched electron beam. This provides a sensitive and nonperturbing measurement of complex Fourier time series components of the electron density. A proof‐of‐principle measurement of the microwave frequency component of electron density in a crossed‐field device, which agrees well with a calculation of the same quantity, is reported.
