Two-color light was irradiated to azo-polymer films to investigate the mechanism of light-induced polymer movement. A collimated green light was used for inducing softening of the polymer, while a focused red light was used for inducing optical gradient force. We found from the topology change of the film that polymer movement was induced only when both green and red light were simultaneously irradiated. This finding indicated that the polymer movement was induced by optical gradient force generated by the red light under the condition that the polymer was softened by repeatable photoisomerization by the green light.
