A scanning type laser induced spectrum surface range analysis and detection system includes a laser emitting head connected to an external laser inducing light source, which 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.

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.
