The feasibility of a high-gain amplifier in an ''optical'' klystron (OK) configuration at wavelengths of 1-2 mm has been investigated. A one-dimensional single-particle model for the free-electron laser (FEL) interaction was used in numerical studies. It was found that for a three-cavity optical klystron, gain greater than or equal to 30 dB and relatively high efficiency are possible for relatively modest electron beam parameters (V less than or equal to 500 kV, J approx. = 100 A/cm/sup 2/).
