We present a novel technique for resonantly pumping a continuous-wave far-infrared NH{sub 3} laser with a line-tunable mid-infrared NH{sub 3} laser that is optically pumped by a CO{sub 2} laser. In this two-step process we first convert 10-{mu}m CO{sub 2} laser photons into 11{endash}13-{mu}m NH{sub 3} laser photons, which are then converted into 60{endash}400-{mu}m photons in a far-infrared NH{sub 3} laser. Continuous-wave laser action on 10 far-infrared lines of {sup 15}NH{sub 3}, including four new ones, has been obtained with a single CO{sub 2} laser pump line. {copyright} {ital 1996 Optical Society of America.}
