A simple technique of obtaining single mode multiline emission from a hybrid CO2 laser is described. This involves operation of its low pressure section below lasing threshold and a judicious positioning of the axial modes with respect to the corresponding rotational line centres. Emission with comparable intensities on up to four rotational lines in the P-branch of the 10 µm band has been achieved. © 1985.
