title: Laser cooling of a direct-current atomic discharge.
abstract: Light-induced heating and cooling of a positive column discharge are demonstrated by combining the optogalvanic and optoacoustic detection. The phenomena that we have observed for laser radiation resonant with several Ne and He transitions are compared with a simplified energy model.
