• We present the results of numerical studies of laser pulse propagating in a 3.5cm Rb vapor cell in the linear dispersion regime by using a 1D model and a 2D code that has been modified for our special case. The 2D simulation finally aimed at finding laser beam parameters suitable to make the Rb vapor fully ionized to obtain a uniform, 10m-long, at least 1mm in radius plasma in the next step for the AWAKE experiment. •Discussion the AWAKE plasma source based on photoionization of rubidium vapor with a TW/cm^2 Intensity laser with a spectrum across valence ground state transition resonances.•Examines the propagation of the AWAKE ionization laser through rubidium vapor at design density on a small scale and reduced intensity with a linear numerical model compared to experimental results.•Discusses physics of pulse propagation through the vapor at high intensity regime where strong ionization occurs within the laser pulse.
