Abstract :
We have made what we think is the first observation of the oscillation of the 9-μm hot-band lines 0111→[111 0,0310]II of CO2. We have observed 40 lines with a maximum power of 8 W. They will provide a new source of laser radiation for spectroscopy. The set of lines has been positively identified by directly measuring the frequencies of two of the lines with a heterodyne technique using a CO2 laser standard
