Coherent effects that occur in the course of amplification of ultrashort pulses in C02-amplifiers may have a significant role in the generation of short C02-laser pulses of a given shape for use in, for example, thermonuclear investigations. To observe the coherent interaction a 1-nanosec C02-laser pulse was formed and propagated through an amplifying medium. A substantial sharpening of the leading pulse front and a splitting into two "2π" pulses is observed. The experimental results are qualitatively confirmed by numerical calculations.
