Abstract: A multi-axis mechanism device includes: a base module, a first moving module, a second moving module, a third moving module, a reaction module, a tilting module and a rotating module. The first moving module performs a first axial movement relative to the movable bearing platform to drive the reaction module to be displaced relative to the movable bearing platform. The second moving module performs a second axial movement relative to the first moving module to drive the reaction module to be displaced relative to the first moving module. The third moving module drives the movable bearing platform to perform a third axial movement relative to the module body to drive the reaction module to be displaced relative to the module body. The reaction module is driven by the tilting module to perform titling action and by the rotating module to perform rotating operation relative to the central axis.

Abstract: A laser-heated cavity system includes: a first cavity provided with a first top end part and a first bottom end part that are arranged opposite each other; wherein the first top end part is provided with a first widow and the first bottom end part is provided with an opening; a second cavity disposed inside the first cavity, provided with a second top end part and a second bottom end part that are arranged opposite each other, and disposed with a second window and a sample bearer; a laser heating assembly disposed outside the first cavity; wherein at least one laser beam provided by the laser heating assembly is passed through the first and second windows, and then focused on the sample bearer; and a mobile platform assembly. The first cavity is a vacuum cavity, and the pressure in the second cavity ranges from vacuum to 30 atm.
