Am. Zheltikov et al., Measurement of electric fields in a plasma with the aid of the coherent four-wave mixing polarisation technique, QUANTUM EL, 29(1), 1999, pp. 73-76
A method for the measurement of a homogeneous static electric field in an i
sotropic homogeneous plasma by the coherent four-wave mixing (FWM) techniqu
es is proposed and theoretically substantiated, The influence of plasma mic
rofields on the intensity and polarisation of the FWM signal is investigate
