Usa green laser pointer will be applied in KTV and night pub

These forces are drawing the particle to the laser waist (light at the most) at the center, therefore, by means of mobile or fixed laser beam clamping particles. Nanomaterials known as the basis of the new 21st century materials, the so-called nano-materials is the particle diameter refers to the material in the material between 1 ~ 100nm. When material particles to achieve this value, due to the surface effect, small size effect and quantum effects, leading to changes in material properties such as reflectivity and melting point decreased and hardness increased. The application of laser technology nanomaterials. Excimer laser ablation of the material has a strong role. It is the double projection   green laser pointer  .
Aluminum under intense laser irradiation, the surface of the plasma cloud injection of oxygen or nitrogen, allows for the creation of Al 203 or AlN particles in diameter, 3 ~ 7nm range, can produce more than ten milligrams per hour. Different composite laser or laser and other energy sources to composite materials processing, mostly used for surface modification of materials processing. Japan's new system of iron CO [_2] laser beam and ion beam, the use of physical vapor deposition technique (LPVD) Preparation of superhard film. Figure 5 is a schematic diagram of the device. Amorphous boron nitride LPVD first system, and then 0.5 ~ 2.0kV irradiation of nitrogen ions can be generated superhard cubic boron nitride films. Two composite laser processing can also be made the special effects, such as CO + KrF excimer laser cutting. The   green laser pointer    has the effect of rotation direction.
Can improve work efficiency 30%, CO 2 laser cut wooden trademarks of mold or carved wood, plastic and other non-metallic decorations, black incision. According to Japanese publication reports that the follow-up to the excimer laser processing, but also to restore the material qualities of. Similarly, for intensive tools such as the excimer laser, or other adjustments Q-switched laser, can greatly enhance the value of the laser processing, laser composite processing is a promising processing method. Industrial lasers laser means for processing, and its development is a prerequisite for the development of laser processing technology. Before the 1990s, CO 2 lasers and YAG lasers accounted for more than 96 percent of the industrial laser, into the 1990s, the development of these two types of lasers is mainly manifested in two aspects of the improvement of power and beam quality.    usa green laser pointer will be applied in KTV and night pub.
CO 2 laser power full one order of magnitude, but really for the production and processing of CO 2 laser power, cutting is generally not more than 3kW, welding in about 10kW. In order to improve the beam quality, fast axial flow CO 2 (Ki-mode output) laser development soon, mainly for cutting and deep penetration welding. YAG laser, the commodity devices power increased from 500W to 1000W. The laser cavity and compressed the divergence angle device, the laser beam divergence angle reduced to below 5 mrad, and improve the focusing power density, enhanced processing capacity. In recent years, following several aspects of both the breakthrough of the laser output power and job stability, so that the laser processing technology has leapt to a new level. The laser projection can take advantage of   green laser pointer    .
Lath (Slab) Nd: YAG laser of the laser structure to overcome the laser rod thermal deformation (thermal lens effect), so the big power (2kW above), the beam divergence angle is small (close to the diffraction limit) of high quality laser output, increase processing capability, ultra-deep processing, such as drilling depth up to 76mm cutting thickness up to 40mm. Laser diode (LD-Laser Diode) pumped Nd: YAG laser the laser with the absorption bands consistent with the YAG spectrum laser diode-pumped Nd: YAG, greatly reducing the non-absorbed light energy conversion with heat, its main feature is electro-optical conversion efficiency (up to 20% ~ 40%), direct access to the UV wavelength of the laser. The weight of   green laser pointer     is 2.9kg.
