Abstract
It is needed to use both Finite Element Analysis（FEM）tool and optical simulation tool to calculate thermal lens effect for optical performance. FEM tool calculates lens internal temperature distribution and surface deformation delivered from laser power absorption and optical simulation tool use these data to calculate optical performance. Since FEM tool handles the data by grid form, on the other hand optical simulation tool handles the data by function form, it is difficult to do co-simulation between two tools. We studied and developed the method to do co-work between two tools easily and accurately and compared the simulation result with measured result and we got good correlation.
