摘要： A compact and efficient ultraviolet laser source based on a optically-pumped solid-state or fiber laser that produces near-infrared output light suitable for nonlinear frequency conversion. The infrared laser output is frequency tripled or quadrupled to produce light in the ultraviolet wavelength range (200 nm to 400 nm). The novel technology is the use of highly efficient periodically poled nonlinear crystals, such as stoichiometric and MgO-doped lithium tantalate and lithium niobate. As opposed to conventional frequency-converted UV laser sources, which have high power consumption, high cost, and low efficiency, the laser sources of this invention utilize high efficiency nonlinear conversion provided by periodically poled materials and allow lower-cost architectures without additional focusing lenses, high power pump diodes, etc.

摘要： A compact, optically-pumped solid-state microchip laser device uses efficient nonlinear intracavity frequency conversion for obtaining low-cost green and blue laser sources. The laser includes a solid-state gain medium, such as Nd:YVO4, and a nonlinear crystal. The nonlinear crystal is formed of periodically poled lithium niobate or periodically poled lithium tantalate, and the crystal is either MgO-doped, ZnO-doped, or stoichiometric to ensure high reliability. The nonlinear crystal provides efficient frequency doubling to translate energy from an infrared pump laser beam into the visible wavelength range. The laser device is assembled in a package having an output aperture for the output beam and being integrated with an optical bench accommodating a laser assembly. The package encloses and provides heat sinking for the semiconductor diode pump laser, the microchip laser cavity assembly, the optical bench platform, and electrical leads.
