  The radiation of pulsars have been observed for many years. A few pulsars are
discovered to have both radio and gamma-ray emission. Many models on pulsar
radiation have been developed, but so far we are still lacking an elaborate
model which can explain the emission from radio to gamma-rays in detail. In
this paper we present a joint model for radio and gamma-ray emission, in which
both the dominate emission mechanisms are inverse Compton scattering. The pulse
profiles at radio and gamma-ray bands are reproduced for the Crab-like,
Vela-like and Geminga-like pulsars, in good agreement with observations.
