As a first test we excite Alkali Rydberg atoms in an electrically contacted vapor cell [1,2]. For a real life application we employ our gas sensing scheme to nitric oxide at thermal temperatures and atmospheric pressure [3]. We report three photon continuous wave laser excitation of nitric oxide to high lying Rydberg states and its conversion into a detectable current in the nA regime.
