We show that a thin film of a three-dimensional topological insulator such as Bi2Se3 or Bi2Te3 can exhibit strong linear and nonlinear magneto-optical effects in a transverse magnetic field. In particular, one can achieve an almost complete circular polarization of an incident terahertz or mid-infrared radiation and an efficient four-wave mixing.
