38.5% optical-to-optical efficiency neodymium-doped yttrium vanadate/magnesium-oxide-doped periodically poled lithium niobate integrated green module with watt-level output power for laser display applications

In this paper, 1.15 W linearly polarized continuous-wave green laser is achieved from a novel neodymium-doped yttrium vanadate/magnesium-oxide-doped periodically poled lithium niobate (Nd:YVO4/MgO:PPLN) integrated packaging module (namely, mGreen) with an optical-to-optical efficiency as high as 38.5%. The presented package module is designed for mass production of green lasers at low cost to overcome the “Green” bottleneck in laser display industry.
