Abstract:
In the present paper graphene nanoflake generator (spaser) is
considered. Consistent derivation of main equations for the description of
graphene spaser dynamics with the account of the material dispersion is
provided. Single-mode equations and rate equations are derived. Explicit
expressions for the parameters in the equations are obtained. Numerical values
of these parameters, which describe graphene spaser dynamics, are given.
