  The reactions gamma gamma -> pi^+pi^-pi^+pi^- and gamma gamma ->
pi^+pi^0pi^-pi^0 are studied with the L3 detector at LEP in a data sample
collected at centre-of-mass energies from 161GeV to 209GeV with a total
integrated luminosity of 698/pb. A spin-parity-helicity analysis of the rho^0
rho^0 and rho^+ rho^- systems for two-photon centre-of-mass energies between
1GeV and 3GeV shows the dominance of the spin-parity state 2+ with helicity 2.
The contribution of 0+ and 0- spin-parity states is also observed, whereas
contributions of 2- states and of a state with spin-parity 2+ and zero helicity
are found to be negligible.
