Calculations of Einstein spontaneous emission coefficients for vib-rotational transitions in HCl laser

Einstein spontaneous coefficients are key parameters of the HCl chemical laser running between vib-rotational transitions in electric ground state,and relate directly to stimulated emission cross-section and small signal gain coefficient.Untied with RKR potential function and the newest EDMF,the program Level developed by Prof.Le Roy of Canady to calculate bi-molecule spectroscopic constants was used to compute the Einstein A coefficients for fundamental band transitions with vibrational energy level of V<6.The database of HCl's A coefficients were retrieved,and it seemed that Level is a rather simple but robust tool for researchers professional in quantum electronics.
