Data are presented on the energy extraction from a transversely excited atmospheric CO/sub 2/ laser amplifier by a 1.1-ns pulse consisting of an adjustable number of lines which are generated by a multiline oscillator of a new design. An increase in energy extraction of 95% with respect to single-line extraction was achieved with a pulse consisting of up to six lines in the 10.6-..mu..m branch. Energy extraction at a fixed number of lines was not very sensitive to their spectral distribution. We observed a maximum increase of about 8% when the lines were spread over the 00/sup 0/1--10/sup 0/0 vibrational band. This indicates a slight preference for small ..delta..j values in the rotational relaxation processes.
