Third harmonic generation by iodine atoms and methyl iodide molecules
B. Katz, Koichi Tsukiyama∥, Richard Bersohn
A dilute gas of I(2Po12) atoms serves as a medium for optical third harmonic generation (THG) of wavelengths a little shorter than 206.2 nm, the wavelength of an atomic transition. It is also shown that a gas of the polyatomic molecule CH3I exhibits THG at wavelengths slightly longer than the first Rydberg transition at 201.2 nm. It is believed that this is a general phenomenon for molecules with sharp Rydberg transitions.
