An electron plasma wave driven by optical mixing of two oppositely propagatingmicrowaves is experimentally studied. The wave amplitude is resonantly enhancedwhen the difference in frequency between two incident electomagnetic waves equalsthe electron plasma frequency. The absolute amplitude and the growth time of the ex-cited waves are found to be 0.8% and 150 nsec (/.Z=50, /.=340MHz), respectively,at the incident microwave power of 40 kW. The wave amplitude obtained experimen-tally is in good agreement with that expected from the optical mixing theory with thedamping term. The dominant damping term is ascribed to the Landau damping ofhigh-energy electrons in the background plasma.[electron plasma wave, beat wave, optical mixing, beating microwaves, Landau ll dampinglll
