We study non-thermal emission process in pulsar magnetospheric accelerator (outer gap). We discuss emissionprocess in optical through 7-ray bands. We solve the dynamics in the outer gap in the magnetic meridional plane, whichincludes the rotation and magnetic axes. We calculate the spectrum of the curvature and synchrotron processes. Using a three-dimensional geometrical model, we compute pulse profile and polarization characteristics. We compare the model results withthe observations of the Vela pulsar and the Crab pulsar. We demonstrate that the observed multi-peak structure of the pulseprofile observed by RXTE can be reproduced by the present study with the outward and inward emissions from the outer gapaccelerator. The calculated polarization characteristics are in general consistent with the Crab optical data.
