The effects of mechanical load on optical properties of Y2SiO5 / Eu:Y2SiO5 crystals are investigated through application of first principles calculations. The crystals are first relaxed to reach equilibrium ground state using plane wave density functional theory (DFT). Once application of load on desired direction is performed the optical absorption profile of aforementioned crystals are plotted with the data provided by Time Dependant Density Functional Theory (TDDFT). The extracted results, not only suggests a directional sensitivity on mechanical strain/load but also it exhibits a sensitivity to the types of exerted stress, which can be immensely important on mounting direction of crystal.
