N2 - We present a form of reversible optical storage in azo-polymer films using optical poling strategy. The experiments consist of an optical seeding process with co-propagating ωM and 2ωM beams where 2ωM frequency serves as an object wave. The storage characteristics for two kinds of systems, namely guest-host and side-chain polymers were demonstrated. It was observed that the recorded image could be stored for long time owing to optically induced quasi-permanent dipole alignment. The paper includes the influence of seeding energy ratio Eω /Eω on optical writing and erasing profiles.
