  The light-by-light (LBL) scattering with initial polarized Compton
backscattered photons at the CLIC, induced by axion-like particles (ALPs), is
investigated. The total cross sections are calculated, assuming CP-even
coupling of the pseudoscalar ALP to photons. The 95\% C.L. exclusion region for
the ALP mass $m_a$ and its coupling constant $f$ is presented. The results are
compared with previously obtained CLIC bounds for the unpolarized case. It is
shown that the bounds on $f$ for the polarized beams in the region $m_a = 1000
\mathrm{\ GeV} - 2000 \mathrm{\ GeV}$, with the collision energy 3000 GeV and
integrated luminosity 4000 fb$^{-1}$, are on average 1.5 times stronger than
the bounds for the unpolarized beams. Herewith, our CLIC bounds are stronger
than all current exclusion regions for $m_a > 80$ GeV. In particular, they are
more restrictive than the limits which follow from the ALP-mediated LBL
scattering at the LHC.
