Hyperfine splitting measurements in the $7d$ $^{2}D_{3/2}$ state of $^{133}$Cs reported using high-resolution Doppler-free two-photon spectroscopy in a Cs vapor cell To do. Determine the hyperfine coupling constants $A = 7.3509(9)$ MHz and $B = -0.041(8)$ MHz. This represents an order of magnitude improvement in accuracy. We also obtain bounds on the magnitude of the nuclear magnetic octupole coupling constant $C$. Furthermore, measuring the ac Stark shift of the $6s$ $^{2}S_{1/2} \rightarrow 7d$ $^{2}D_{3/2}$ transition at 767.8 nm yields $-49 \pm 5$ Hz/(W/cm$^2$), consistent with theoretical calculations.In addition, we report measurements of the collisional shift [$-32.6 \pm 2.0$ kHz/mTorr] $6s$ $^{2}S_{1/2} \rightarrow 7d$ $^{2}D_{3/2}$ Pressure broadening of individual hyperfine levels of the transition.These measurements are from the cesium $6s$ $^{2}S_{1/2} \rightarrow 7d$ $^{2}D_{3/2}$ two-photon transition
