Precision measurement of the Stark shift in the 6S1/2→6P3/2cesium transition using a frequency-stabilized laser diode

We employ crossed-beam laser spectroscopy with a frequency-stabilized laser diode to measure the Stark shift of the 6$P_{3/2}$ state relative to the ground state of atomic cesium. The scalar and tensor polarizabilities are determined from the measured Stark shifts in the transitions 6$S_{1/2}$ F=4→6$P_{3/2}$ F’=5, $M_F$=5 and 4. Our results are ${\mathrm{\alpha }}_0$(6${\mathit{P}}_{3/2}$)+${\mathrm{\alpha }}_2$(6${\mathit{P}}_{3/2}$)-${\mathrm{\alpha }}_0$(6${\mathit{S}}_{1/2}$)= 977.8(19)${\mathit{a}}_0^3$ and ${\mathrm{\alpha }}_2$(6${\mathit{P}}_{3/2}$)=-262.4(15)${\mathit{a}}_0^3$.
