Using the electro-optic detection method we have detected coherent phonons of Eg1, Eu1, Eg2, and A1g1 symmetry generated in a crystalline film of Bi2Se3 by a powerful single-cycle THz pulse. Coherent excitation of Raman active modes is interpreted as a result of three-and four-phonon interactions in the anharmonic crystal lattice of Bi2Se3.
