Abstract: We examine a contribution of axion-like particles (ALPs) to a top pair production via the collision of Compton backscattered photons at the CLIC operating in a $$\gamma \gamma $$ γ γ mode. The exclusion bounds on the ALP-top quark coupling depending on the ALP mass $$m_a$$ m a are given. The mass range 10 GeV–10 TeV is considered. We have obtained that for $$m_a = 10$$ m a = 10 GeV the ALP-top quark couplings are as small as 0.17 $$\hbox {TeV}^{-1}$$ TeV - 1 and 0.11 $$\hbox {TeV}^{-1}$$ TeV - 1 can be probed at the CLIC with the energy of 1.5 TeV and 3 TeV, respectively. A comparison with other constraints on the ALP-top coupling is given.
