So this is a high-speed rapid prototyping technology. Parts the greater the volume, the higher the efficiency. Processed parts can be used directly, without the need for correction. Without the need to design and build the support structure. Easy to use, and pollution-free. Disadvantages: less the type of practical application of raw materials, although the choice of certain raw materials such as paper, plastic, clay and synthetic materials, but the common paper, foil material suppliers in the research and development. The paper part is easy to absorb moisture, must be carried out immediately after processing, painting. Difficult to build the fine shape of the parts, is limited to the simple structure of the parts.
So far, in the military field, the laser has been widely used in directed energy weapons, many areas of aerospace, surveillance and counter-surveillance, guidance, communications, greatly improving the combat and defense capabilities of the armed forces under conditions of high-tech war. At the same time, the laser conversion technology has also been a great development. Wide range of laser applications. Laser application is the use of laser directivity and good monochromaticity, high brightness and high spatial and temporal coherence characteristics of the scientists are optimistic. In the military field, the laser can be used to implement conventional strike ignition in the aerospace propulsion control burning, reconnaissance and counter-reconnaissance, precision-guided, secure communications and aircraft attitude and orientation. The laser weapon is a directional emission of the laser beam directly damage the target, or the failure of directed energy weapons. Depending on the operational use, the laser weapons can be divided into two major categories of tactical laser weapons and strategic laser weapons. Weapon system by the laser and tracking, targeting, launchers and other components, the commonly used laser chemical lasers, solid-state lasers, CO2 lasers. The laser weapon attack speed, steering and flexible, and can achieve a precision strike, and immunity to electromagnetic interference, etc., but there are also vulnerable to weather and environmental impact of weaknesses. It shows the design structure of green laser pointer .
Penetration of blue-green sea water up to 600m above its propagation direction, and not to be intercepted by the enemy, and covert security, will greatly improve the Navy of its viability. Laser communications, however, there are some shortcomings, such as laser intensity attenuation in the transmission medium, the laser beam divergence problem, to overcome this problem is subject to the further development of laser technology. Optical fiber communication technology, is based on a monochrome laser and wide bandwidth nature of the development of mature. Light as the carrier of the communication has been successfully serving our community. Laser ranging.
