The total cross sections for the π+π- photoproduction on the deuteron were measured in an energy range of 0.8 to 1.1 GeV. The obtained total cross section for the quasi-free π+π - photoproduction on the deuteron was about 60 % of those on the free proton. The cross section for Δ++Δ- photoproduction was derived from the non-quasi-free π+π - photoproduction events. It was smaller than the previous data.
