%X In this paper, the dynamic properties and the spontaneous emission spectrum of V-type three-level atom near left-handed material slab are investigated. The two orthogonal dipoles of the decay from the two upper levels to the lower level are considered. Due to the focusing and the phase compensation effects of the left-handed materials, the indirect quantum interference between two orthogonal spontaneous emission transitions leads to the fact that the populations in the two upper levels influence each other, the decay rate is enhanced or decreased and the spontaneous emission spectrum is narrowed or widened, depending on the initial atomic state.
