    摘要: A large-aperture laser amplifier side-pumped by a multi-dimensional laser diode stack, which comprises: multiple pumping light source assemblies; a laser medium, of which the shape is a prismoid, wherein both the upside surface and the underside surface of the prismoid are polygonal, and the number of the edges of the polygon is the same as the number of the pumping light source assemblies; and a cooling device. Each side of the laser medium is provided with a pumping light source assembly; the pumping light emitted from the semiconductor laser diode stack is shaped by the beam shaping element, coupled by the coupling duct, and then enters from the side of the laser medium for side-pumping, and thereby amplifying the laser beam incident from the upside surface of the prismoid of the laser medium.

    摘要: The present disclosure discloses a scanning type laser induced spectrum surface range analysis and detection system. A laser emitting head is connected to an external laser inducing light source. The external laser inducing light source generates lasers emitted through the laser emitting head, so as to generate laser induced plasma. A focusing optical device converges induction excited laser beams emitted by the laser emitting head onto a surface of a tested sample. Then, a reflector collects wide spectral range induced plasma scattered light signals of the tested sample and converges the signals into a light collecting device. The light collecting device converges induced plasma scattered light into an optical fiber and transmits the induced plasma scattered light to an external spectrograph; and the external spectrograph divides a spectrum formed by the plasma to obtain spectral strength data of different wavelengths. Therefore, the spectral collection of a wide range of several hundreds of nanometers is performed in the same optical axis; and the large energy laser induction in Joule level can be carried with an efficiency higher than 90%.
