Abstract: Defects production and evolution in H and He ions co-implanted LiTaO3 under different implantation order (H + He and He + H) are investigated. Rutherford backscattering spectrometry (RBS), infrared (IR) spectroscopy and transmission electron microscopy (TEM) are used to study the lattice damage, composition and structure change in the buried damage region. Obvious differences of ions aggregation mechanism are found in H and He implanted LiTaO3. Blistering or splitting of LiTaO3 is more easily achieved in the case where He is implanted first compared to the reverses case. Significant damage enhancement and micro-fractures are observed in samples with He preimplant. The dispersed damage in H-first sample is due to the destruction by He post-bombardment of H-clusters. This order effect indicates the strong aggregation and trapping ability of He ions and He bubbles. The effect of coimplantation parameters on the cleaving of LiTaO3 is discussed
