As LED lighting made it obvious, visible light can be generated by LED pumping of phosphors or fluorescent crystals such as Cerium-doped YAG crystal (Ce:YAG). However, the relatively big emitting area of pumping LEDs and highly divergent light cone of fluorescence emission result in light sources of very large optical etendue (product of emitter size and light cone) that are not suitable for effective coupling into small core diameter optical fibers required in optogenetic experiments and elsewhere. Consequently, we designed a fluorescent light source, called the Ce:YAG Fluorescence Light Source, in which a Ce:YAG crystal is pumped with multiple high-power blue laser diodes instead of blue LEDs. This concentrates excitation and fluorescence emission in a very small area of the Ce:YAG crystal. As shown in the figure below, this patent pending laser diode pumping geometry significantly increases the fiber coupling efficiency compared to conventional light sources such as incandescent lamps or LED based light sources.
