 Laser Pointer can be directly used in the club.
For low-power lasers, work uniform and stable material, the general base model output can be achieved, the energy distribution of the beam cross-section for the Gaussian distribution, and in the transmission process remains the same, better beam quality; for high-power lasers, generally difficult to obtain fundamental mode output, the output is often a multi-mode laser beam, laser beam quality deterioration. Commonly used in industry for high-power CO2 laser and YAG laser with laser two.  Laser Pointer should gain the approval before delivery.
High-power lasers for industrial applications is very broad, laser cutting, laser welding requires good beam quality, and the pursuit of high quality, high-power laser beam is the continuous development of industrial lasers target. From 1964, the first CO2 laser appears to now, after nearly four decades of development, from the sealed off CO2 laser, slow axial flow CO2 lasers, transverse-flow CO2 lasers, to high-frequency fast axial flow pump Rhodes, RF fast axial flow turbo-type as well as the spread of the present situation of the development of type Slab CO2 lasers can be seen, on the one hand increasing the laser output power, volume shrinking on the other hand increasing the efficiency of the laser beam quality is getting better. The design of Laser Pointer has been approved.
Diffusion Slab CO2 laser beam cross-section intensity distribution close to Gaussian distribution (Figure 2), with excellent beam quality of laser processing in the work area to increase the focus of the drift is very small, very beneficial to a wide range of laser transmission and aggregation, which is the large size of the workpiece cutting applications is very important. Industrial solid YAG laser has also experienced a small power lamp-pumped (ROD), lamp-pumped (lath), dual-lamp-pumped (multi-rod) to the optical pump (ROD), diode-pumped (ROD) and sheet the process of solid-state lasers. Work due to the constraints of thermophysical properties of material, YAG laser mode beam quality is relatively poor. How to improve the beam quality and laser power, is still the main problem facing the YAG laser. The approval of manufacturing Laser Pointer is not that hard to gain.
It is noteworthy that in recent years developed semiconductor lasers. Semiconductor lasers with small, high frequency, coupled with good fiber, easy-to-excellent modulation characteristics, and therefore has broad application prospects.
