Abstract
A large aperture uniform-amplification laser module including a longer, larger diameter crystal bar is disclosed. The laser module includes a ring-shaped pump bar structure, a crystal bar, a glass sleeve, and a structural component. The pump bar structure includes pump blocks composed of a bar, a cooling heat sink, and a cooling pipe. The bar is connected with the heat sink, and a cooling water channel is provided inside of the cooling heat sink. Heat sinks are provided with outlet pipes and an inlet pipes to communicate with water channels, which are connected in series through the cooling pipes to form a ring shape. The bar is close to a center axis of the ring-shaped pump bar structure. The crystal bar is provided in the glass sleeve. A plurality of the ring-shaped pump bar structures are sleeved on the glass sleeve along the length of the glass sleeve.
