Tunable HF (DF) laser initiated by pulse CO2 laser radiation

The laser action was achieved as a result of the initiation of chemical reactions in SF₆ + H₂, SF₆ + C₃H₈, and SF₆ + D₂ mixtures by pulse CO₂ laser radiation. The emission spectrum was recorded and tuning was achieved by selecting one vibration-rotational transition in the range 3200–3700 cm^–1 in the case of HF and in the range 2450–2650 cm^–1 in the case of DF.
