Outline of Final Research Achievements

Nonlinear interaction at the collision point of counter-propagating pulse-shaped spatial solitons has been investigated to develop three-dimensional optical processing with the high spatial resolution at the depth of optical materials. Phase-contrast scanning optical microscope using long working distance objective lens was built in the experimental system, and absorptive and phase-contrast images of the structures in the materials were experimentally obtained. Also, the finite-difference time-domain method considering the periodic energy transfer between the fundamental beam and its second-harmonic beams were developed, and the self-trapping effects and collision response of the counter-propagating spatial solitons were numerically analyzed.
