Investigation of spectral and time characteristics of a HF chemical laser

Calorimetric receivers were used in a study of the distribution of energy between vibrational-rotational transitions in the P branch of the HF molecule in the radiation emitted from a F₂–H₂–O₂–He laser. The time dependences of the output radiation were studied with photoresistors. The results obtained were used in an analysis of the elementary processes occurring during stimulated emission.
