Claim:
1. A large aperture uniform-amplification laser module, comprising: a ring-shaped pump bar structure; a crystal bar; a glass sleeve; a structural component, wherein the pump bar structure comprises a plurality of pump blocks, and each pump block is composed of a bar, a cooling heat sink, and a cooling pipe, wherein the bar is connected with the cooling heat sink, and a cooling water channel is provided inside of the cooling heat sink, wherein two of the cooling heat sinks are respectively provided with an outlet pipe and an inlet pipe which are communicated with the cooling water channel, wherein from the cooling heat sink provided with the inlet pipe to the cooling heat sink provided with the outlet pipe, a plurality of the cooling water channels are connected in series through a plurality of the cooling pipes and form a ring shape, wherein the bar is close to a center axis of the ring-shaped pump bar structure, wherein the crystal bar is provided in the glass sleeve, wherein a plurality of the ring-shaped pump bar structures with the same diameter or different diameters are sleeved on the glass sleeve along the length of the glass sleeve, wherein the glass sleeve is fixed, through the structural component, at a hollow part which is composed of a plurality of the ring-shaped pump bar structures, wherein a gap is between an outer wall of the glass sleeve and each bar of each pump bar structure, wherein each pump block is correspondingly provided with an electric control block and a retractable screw, wherein the cooling heat sink in the pump block is connected with the electric control block through the retractable screw, wherein the electric control block controls, according to an electrical signal provided from outside, the rotation of the retractable screw to adjust the distance between the bar and the crystal bar; and a housing for respectively fixing each electric control block.
