Abstract Plasma-based optical elements, including ponderomotive plasma lenses, offer distinctive capabilities for energy steering, localization, and high-sensitivity imaging in dynamic media. In this work, we investigate the application of ponderomotive plasma lenses to holography by utilizing the interference of two Gaussian laser beams. The analysis focuses on how the collective plasma response to spatial intensity gradients leads to refractive index modulation and dynamic wavefront control. By explicitly defining the holographic geometry and distinguishing between the reference and sample beams, we show that the achievable image resolution is strongly influenced by the transverse properties of both Gaussian inputs. In particular, the beam widths play a central role in determining the coherence, stability, and spatial-frequency content of the interference pattern. Appropriate adjustment of the individual beam waists improves fringe quality and phase sensitivity, resulting in enhanced spatial resolution and more accurate reconstruction of the three-dimensional refractive-index distribution. The present study is theoretical and employs laser parameters that are accessible in laboratory-scale systems, providing a physically realistic basis for plasma-based holography using standard solid-state laser sources.
