Abstract :  In this study, triple Higgs boson production channels in a γγ-collider are investigated in the context of the two-Higgs-doublet model insert ignore into journalissuearticles values(2HDM);. This model has three neutral Higgs bosons insert ignore into journalissuearticles values(h 0 /H 0 /A 0 ); and two charged Higgs bosons insert ignore into journalissuearticles values(H ± );. Between all the possible combinations of the triple Higgs bosons in the final state, only the following two scattering processes are probable at tree-level: γγ → H + H - h 0 and γγ → H + H - H 0 . These two processes are important to determine the triple Higgs self-couplings g H + H - h 0 and g H + H - H 0 in the 2HDM. The calculation is carried out for two scenarios, which are inspired by recent experimental and theoretical results. The cross-section of these processes is calculated and a comparison is made for these scenarios. The total convoluted cross-section with photon luminosity in an e + e - -collider is presented as a function of the center of mass energy.
