Nineteen new laser lines in the 11-{mu}m wavelength region have been observed in cw oscillation from a CO{sub 2} laser with a high-Q. high-resolution cavity at a higher than usual current density. The frequency of each line has been measured using heterodyne frequency measurement techniques. Analysis of the frequencies shown that 15 lines are rotation-vibration transitions of the 01{sup 1}2-[11{sup 1}1.03{sup 1}1]{sub I} band (the first sequence hot band) of the CO{sub 2} molecule and four lines belong to the rotation-vibration transitions of the 02{sup 2}1-[12{sup 2}0.04{sup 2}0]{sub I} band of CO{sub 2}.
