The results of the theoretical study of lasing in hollow cathode discharge (HCD) plasma are presented. The ion metal transitions were excited by second-kind collisions at HCD of noble gas-metal vapor mixtures, such as He-Be, Ar-Ca, Kr-Ca, Kr-Sr, Ne-Ga, Ne-In, He-In, Ne-Tl, and He-Tl. The dependences of the level population densities, gain and specific laser output power on HCD parameters are calculated. As a result, the lasing on 38 new transitions in the infrared wavelength range of 689…3724 nm were predicted. Studied lasers can become effective sourses of radiation for using in metrology
