Modeling a laser - driven white light source with curved phosphors

In this work a simulation software is employed to study how the different shapes of the phosphor material may affect the white light production of the light source. In particular, while usually the phosphors that are being used in a laser driven configuration are flat plates, in this case we examine what happens when curvature is introduced. It is shown that curvature affects the way the produced white light is distributed and it can also increase the conversion of laser light to white light by the phosphor due to its curved shape. Sample phosphors of different curvature and geometry were studied and compared to the flat shaped ones.
