A CH$sub 3$F amplifier has been constructed for use with a narrow- linewidth pulsed 496-$mu$m CH$sub 3$F cavity laser. The power conversion ratio of the amplifier, defined as the ratio of 496-$mu$m power emitted to CO$sub 2$ power absorbed, had a maximum value of (4.7+-2.5) x10$sup -3$ at a CH$sub 3$F gas pressure of 0.1 torr. The highest average power, 6+-1 kW, was produced by the oscillator-amplifier laser system when the amplifier was run with a CH$sub 3$F gas pressure of 0.9 torr. At this pressure the power conversion ratio of the amplifier was (1.8+-1.0) x10$sup -3$. Analysis of the gain data yields values for the small-signal gain and saturation intensity as a function of CH$sub 3$F gas pressure. (AIP)
