The influence of laser polarization angle on the photodetachment of H- near a reflecting surface is investigated based on a theoretical imaging technique. An analytical expression for the photodetachment cross section is derived. The photodetachment cross section of H- near a reflecting surface is found to be not only related to the inter-ion-surface distance and the photon energy but also the laser polarization angle theta (L) . A strong oscillating structure is noted for theta (L) = 0A degrees. As the angle continues to increase, the oscillating structure diminishes, and for theta (L) = 90A degrees, the oscillating structure in the cross section reduces to a non-oscillating structure.
