The dc Stark shift of the lithium D1 line has been observed using two visible diode lasers and an atomic beam. A heterodyne signal obtained from the two lasers permits a well-calibrated, high-precision measurement to be made. The scalar shift is found to be 4.6216(21) kHz/(kV/cm ${)}^{2}$ . We believe this result to be the most precise Stark shift measurement reported thus far.The dc Stark shift of the lithium D1 line has been observed using two visible diode lasers and an atomic beam.
