Optic thin film with high refractive index and high laser damage threshold was prepared from ZrＯCl2·8H2Ｏ with solgel process. The film was prepared with spin coating method. The structure, optical properties and laser damage threshold of the films were investigated. The influences of organic binder to the refractive index and the mechanic strength of the films were also studied. A minimum transmittance of less than 1% near 1064nm was obtained from the present ［SiＯ2/ZrＯ2］１０multilayer HR coatings, meanwhile a laser damage threshold of more than 16J/cm2 was achieved using high power laser at wavelength of 1064nm and pulse width of 2.5ns.
