Abstract
Possible tests of the CP-violating triple gauge bosons couplings in ga mmagamma --> WW and egamma --> Wnu are discussed. Using either circula r or linear polarization of the initial photon laser beam, direct meas urements of CP-odd observables in gammagamma --> W+W- are possible. We obtain limits on the coefficient of the CP-violating coupling of R(f6 ) < 0.9 x 10(-2) and J(f6) < 5.4 X 10(-4) for square-root s = 1 TeV. T hese are then compared with the limits obtained from the total cross s ection with or without polarized beams in gammagamma and with differen t asymmetries in egamma.
