Abstract

During the reaction H(Dz)+F2 similar quantities of the chemical interaction energy are spent on the excitation of vibrational and rotational levels of 1W and DF molecules. However the known energy characteristics of pulsed chemical DF laser are 2—3 times lower than those of the HF laser [1J. It is connected on opinion of various researchers with larger (as compared with hF) number of vibrational arid rotational levels of molecule I)F among which the energy of chemical reactions is distributed with smaller values of Einstein coefficients and rate constants of chain reaction. lt results in lower value of gain for majority of vibrational-rotationai transitions of DF molecule. Therefore for extraction of laser energy from active medium of DF laser an optical resonator with small losses is required.
