Communication subsystem Aside from achieving high-speed, high-power transmitters and broadband high-sensitivity receiver, will be the communication beam divergence angle is very narrow beam emission (near the diffraction limit, usually more than a dozen micro-radian magnitude). This is a space laser communication is the basis of long-range, light and small, high-speed communications capabilities. Space laser communication system after nearly 20 years of rapid development. Many of the key technologies in the system has made a breakthrough. At present, the international community has successfully carried out the demonstration of multiple links, but there are the distance from the actual T-way applications, The one hand, its small way, maturity, reliability, also need to further improve. On the other hand, is the communication rate is still not fully play the advantages of optical communication technology. They are in charge of the draft and preparation of Green Laser 5MW.
Also need to continuously improve to meet the needs of modern information technology. With the development of high-tech, underwater fishing, detection, control needs, and gradually formed a special underwater communication applications. Absorption of seawater on the high frequency of strong electromagnetic waves, electromagnetic wave energy attenuation in the water is very serious, almost impossible to pass through the sea spread, resulting in the invalidity of the traditional waves in underwater communications applications. The invention of the laser and applications for the development of optical communications, and more underwater optical communication has brought the gospel, a high data transfer rate, excellent confidentiality and robustness of underwater communication of great strategic significance. The workshop can use the drawing of laser pointers as the guide.
The United States on the basis of several maritime laser submarine communication test, carried out a comprehensive demonstration onboard the submarine communication plan off the ground only a few hundred kilometers of low-cost, low-orbit satellites with high-power solid-state lasers, instead of previous plans to use geostationary satellites to carry out the duplex satellite - submarine laser communication system. Laser application in the field of medicine and research progress. The laser is a strong direction, performance monochrome and highly concentrated coherent light beam, the use of the lens can be focused to very small points of light, its energy density is very high on the spot, and in a few microseconds or a few ms within the laser spot after by focusing up to tens of microns in diameter. Zumba Fitness DVD As the laser technology of laser pointers develops.
To adjust the amount of reactive oxygen species (reactive oxygenspecies, ROS); protein molecules on the cell membrane mediated by PBM of non-specific pathways, signal transduction and gene expression regulation, subject to a bio-information model of PBM. Medical lasers use high-intensity laser (tugh intensity laserirradiation.HIL) of high-intensity light and heat effect, shock waves and photoacoustic effect for surgery. The HIL surgery and the PBM in medical applications are almost always developed independently. The HIL beam center intensity is very high, which may damage cells within the damage radius, but the average intensity of the beam outside the damage radius of a low-intensity range, can produce the PBM cells other than the damage radius. Therefore, the manufacturer has been paying more and more attention to enhancing and improving the quality and performance of this kind of laser pointers.
Outside the radius of the the HIL beam damage part of the PBM cells without damage arising simply known as high-intensity laser biological regulation (HILbiomodulation HBM). HIL beam damage within a radius of resected tissue; the HBM outside the damage radius depends on the average dose of HIL in the outside of the damage radius, can promote the growth of the remaining organs and even restore the normal function of the organ, or inhibit the growth of the remaining organizations. Laser in industrial applications and research progress. Laser because of the monochromaticity, coherence, and parallel to the three major advantages, this applied to materials processing, the formation of a new processing industry - the laser industry. laser pointers can be used to burn the match or the black material directly.
