In this report, the cyclotron-phonon resonance (CPR) in monolayer graphene via two-photon absorption process is investigated when electrons are scattered by zone-center and zone-edge optical phonons. Using perturbation methods, we obtain the expression of the diagonal conductivity.. Resonances are separated into three types: principal, symmetric, and asymmetric transitions in which the principal transition gives dominant contribution to the CPR diagonal conductivity. The inter-band scattering gives higher contribution to the total CPR conductivity in comparison with the intra-band scattering.
