Abstract

Population densities for the excited levels of hydrogen-like ions in an optically thin plasma have been calculated in order to investigate the appropriate conditions for the generation of population inversion by recombination and subsequent development of gain in laser systems. To achieve this goal, collisional-radiative model in a range of electron temperature of 4000Z² - 256000Z² ⁰K and electron density of 10⁸ Z⁷ - 10¹⁸ Z⁷ cm^-3is used. In addition, the inversion threshold temperature is introduced and used in characteristic graphs which helps to identify the inversion conditions.
