Abstract

A laser-activated remote phosphor (LARP) target with a first layer having a first index of refraction and a phosphor dispersed within the first layer. A second layer which has a second index of refraction different from the first index of refraction and adjoins the first layer at an interface. The first index of refraction is higher than the second index of refraction such that the interface is configured to at least partially reflect light emitted from the phosphor.
