Besides the SM-like Higgs boson h, the Higgs triplet model (HTM) predicts the existence of charged and doubly charged Higgs bosons ( and ). In this letter, we focus on the study of the triple Higgs production in γγ collisions at the high-energy linear collider: and . We present the production cross-sections and the distributions of the various observables, i.e., the distributions of the energy and the transverse momenta of the SM-like Higgs boson and charged Higgs bosons. Our numerical results show that, with reasonable parameter values, the values of the cross-sections for two processes can reach the level of several tens of fb and hundreds of fb, respectively. Due to the small SM background, the possible signals of and might be detected via these processes in the future high-energy linear-collider experiments.
