High energy heavy ion irradiation has been performed in LiTaO₃ in a broad set of experimental conditions to study the synergistic effects in the damage generation between the nuclear and the electronic energy loss mechanisms. Optical waveguides have been fabricated in LiTaO₃, using 20–25 MeV F and 40 MeV Si ions, and their refractive index profiles were used as a very accurate method for the in-depth damage profile determination and its correlation with the energy loss curves. In-situ optical reflectance of low energy irradiations (500 keV F and 300 keV Si ions) has been performed to estimate the nuclear damage kinetics of the buried regions of the high energy irradiations that are not optically accessible with the optical waveguide characterization in the fluence regime when the electronic damage is intense. The angle of incidence has been varied to enhance the damage and further ascertain the existence of a synergistic mechanism.

在广泛的实验条件下，已经在LiTaO ₃中进行了高能重离子辐照，以研究核能和电子能损失机理之间的损伤产生的协同效应。在LiTaO _3中制造了光波导，使用20–25 MeV F和40 MeV Si离子，并将它们的折射率分布图用作确定深度损伤分布图及其与能量损失曲线的相关性的非常准确的方法。已对低能量辐射（500 keV F和300 keV Si离子）进行原位光学反射，以估计高能量辐照掩埋区域的核破坏动力学，这些能量在光通量中无法通过光波导特性进行光学访问电子损坏严重时的状态。入射角已经改变，以增强损害并进一步确定协同机制的存在。
