| titleOfInvention | VCSEL-based pumping light source and preparation method |
| abstract | The invention discloses a VCSEL-based pumping light source and a preparation method thereof, wherein the preparation method comprises the following steps: the two-dimensional VCSEL array chip comprises a two-dimensional VCSEL array chip, a substrate layer and an optical coupling system; the two-dimensional VCSEL array chip is arranged at the bottom of the substrate layer; a plurality of grooves are etched in the top of the substrate layer along the laser emitting direction, and a first material is filled in the grooves to form a filling layer; the refractive index of the first material is higher than that of the substrate material, and the absorption rate of the emitted laser light of the VCSEL is lower than that of the substrate material; the top of the substrate layer is connected with an optical coupling system, and the optical coupling system focuses the emergent laser of the two-dimensional VCSEL array chip into a fiber laser or a solid laser pumped by a semiconductor laser. According to the invention, the groove is etched in the substrate layer, and the material which has a refractive index higher than that of the substrate material and has a lower absorption rate to laser emitted from the VCSEL than that of the substrate material is filled in the groove, so that the loss of the VCSEL as a pumping source can be reduced. |
