in this paper, we examine the potentials of the processes gamma gamma -> W(+)W(-)Z: and e(+)e(-) -> e+gamma*gamma*e(-) -> e(+)W(+)W(-) Ze(-) at the CLIC with root s = 0.5, 1.5 and 3 TeV to investigate anomalous quartic W W Z gamma couplings by two different CP-violating and CP-conserving effective Lagrangians. We find 95(X, confidence level sensitivities on the anomalous coupling parameters at the three CLIC energies and various integrated luminosities. The best sensitivities obtained from the process gamma gamma -> W(+)W(-)Z on the anomalous k(0)(w)/a(2) , k(c)(w)/a(2) and k(2)(m)/a(2) couplings defined by CP-conserving effective Lagrangians are [-1.73; 1.73] x 10(-7) CeV-2, [-2.44; 2.44] x10(-7) and [-1.89; 1.89] x 10(-7) GeV-2, while a(n)/A(2) coupling determined by CP-violating effective Lagrangians is obtained as [-1.74; 1.741 x 10(-7) GeV-2. In addition, the best sensitivities derived on k(0)(w)/a(2) , k(c)(w)/a(2) and k(2)(m)/a(2) and a(n)/A(2) from the process e(+)e(-) -> e(+)gamma*gamma*e(-) -> e(+)W(+)W(-)Ze(-) are obtained as [-1.09; 1.09] x 10(-6) GeV-2, [-1.54; 1.54] x 10(-6) GeV-2, [-1 1.18] x 10(-6) and [-1.04; 1.04] x 10(-6) GeV-2, respectively.
