Abstract: Provided are conveying apparatus and tinting apparatus. Conveying apparatus includes: first guide rail, including first section and second section connected to each other; compression module, movable along first guide rail and provided on first guide rail in fitted manner, compression module including base and compression assembly having adjustable relative positions, compression assembly being provided on base, gap existing between compression assembly and base, compression module having to-be-assembled state and compression state, and when compression module is in compression state, gap being narrowed to tightly clamp clamped member; and limiting structure, during compression module moves from first section to second section, state of compression module being switched by means of limiting structure, when compression module is located on first section, compression module being in to-be-assembled state, and when compression module is located on second section, compression module being in compression state.

Abstract: A solid laser apparatus which includes: two reflection elements for forming an oscillator; a plate-shaped gain medium being disposed between the two reflection elements, thereby augmenting a stimulated emission light in a thickness-wise direction; a doughnut- or deformed-doughnut-type planar waveguide being disposed so as to make an inner peripheral face thereof come in contact with an outer peripheral face of the plate-shaped gain medium; and a plurality of excited-light sources being directed in five or more directions, the excited-light sources being coupled to an outer peripheral face of the doughnut- or deformed-doughnut-type planar waveguide so as to make excited lights propagate from the outer peripheral face of the doughnut- or deformed-doughnut-type planar waveguide to the plate-shaped gain medium.
