Laser emission on the sequence bands of CO/sub 2/ has been achieved in a TEA amplifierusing either a hog-CO/sub 2/ cell or a Michelson interferometer to prevent oscillation of the regular bands. It has been found that the interstation losses of the hot-CO/sub 2/ filter severely limit the energy extraction efficiency on the sequence bands. With the Michelson arrangement, output energies of 140 mJ on the sequence P (17) have been produced in a 33-cm-long TEA amplifier. The relatively low efficiencies obtained suggest that generations of high-intensity laser beams at the sequence band frequencies would require the use of oscillator-amplifier combinations.
