We report on the first online observation of invisible plumes in the CO2 laser system by use of a CEDIP Instruments Inc. infrared camera. Examples of movie clips of the flame are presented. We also present results of ingenious experiments on spectroscopy of such flames by means of an RS Series of the BOMEM FTIR employing two types of the Cincinnati Electronics Laboratories IR detectors operating at liquid nitrogen temperature. The spectra show new absorption peaks. Temperatures vs laser power and vs laser wavelength are presented
