Single crystal phosphor has been developed with superior material performance for conversion of blue laser light into yellow visible light providing high efficiency, high temperature operation, and operation in a larger volume waveguide form for ease of heat sinking. This paper presents an end-pumped structured crystal phosphor waveguide design such that the volume of laser absorption and heat dissipating surfaces are both larger with a small output cross-section for small etendue operations. Preliminary samples have been fabricated with expected results. Several structures and measurement results will be presented.
