In a microwave argon plasma, the electron-impact population transfers between the first four excited states of argon are studied by time-resolved laser pump-probe technique. Metastable atoms in the 1s(5) state (in Paschen's notation) are selectively pumped up to the 2p(3) state, with a nanosecond pulsed dye laser tuned to the 706 nm argon transition and the temporal response of the densities in the 1s(3), 1s(4) and 1s(5) states are monitored by time-resolved laser diode absorption. The electron density and temperature are also measured by Thomson scattering along the plasma column for different pressures. The rate coefficient measured for the 1s(3) to 1s(2) state transfer, for which only rough estimations exist in the literature is found to be 9 x 10(-13) m(3) s(-1), almost five times larger than the value commonly assumed.
