Abstract

The Stark shift in the visible absorption spectrum of a homonuclear diatomic molecule has been observed for the first time to the author’s knowledge in molecular iodine through the use of Stark modulation spectroscopy. The Stark modulation technique is proposed for a new method of stabilization of a visible laser frequency on the I₂ or ICl absorption lines.
