Popis:	Using a thallium atomic beam apparatus and a stabilized, frequency-doubled diode laser system, we have measured the scalar Stark shift in the ${6P}_{1/2}\ensuremath{-}{7S}_{1/2}$ transition of thallium. We determine the Stark shift to be $\ensuremath{\Delta}{\ensuremath{\nu}}_{S}=\ensuremath{-}103.23(39)\mathrm{kHz}/(\mathrm{kV}/\mathrm{cm}{)}^{2},$ providing more than an order of magnitude improvement in precision over earlier measurements of this quantity. This measurement serves as a stringent test of recently published thallium parity nonconservation calculations.
