It is convenient to update the green laser pointer system
Over the last decade, such as Freon HCFC containing a large number of emissions, making the concentration of the ozone layer over Antarctica is almost cut in half, forming the so-called ozone hole. If the hole has expanded, the Earth will lose the solar ultraviolet radiation shielding capabilities, which led to life imbalance, so closely monitor the ozone concentration over Antarctica to study the variation and its causes is necessary, usually with a scattering of differential absorption lidar for monitoring of resonance fluorescence detection of the upper atmosphere in laser radar in terms of atomic composition showed a clear advantage,The green laser pointer would be no longer within the quality guarantee range if it is damaged by being kept in wrong environment such as an environment with low temperature. the thin air at this time because the upper atmosphere, coupled with the atomic scattering cross section is much larger than the molecule, so the resonance fluorescence effect prominent. with a flash pump Rhodamine 6G dye laser and receiving aperture 97 cm reflector, a high signal to noise ratio can be found in the 90 km to 100 km altitude sodium layer near the addition, lidar can also be used to detect the wind, turbulence and particulates that if the laser radar installed on the satellite, it can detect atmospheric temperature, humidity and air pressure, so that to obtain more extensive global weather satellite weather data The green laser pointer would be no longer within the quality guarantee range if it is damaged by being kept in wrong environment such as an environment with high humility.Second, high-power laser energy can not be optimistic about the current international environment, energy, fossil fuel shortages began to appear to present Some of the energy to estimate, within about a hundred years will suffer energy shortage crisis, which on the whole progress of human civilization is a great threat even if no shortage of fossil raw materials, the burning of fossil raw materials produced by a large number of greenhouse or other environmental pollution problems, let us beg to differ now more optimistic about solar power generation efficiency can reach 20%, but Taiwan to rely on solar power to meet demand, must be a quarter of the area coverage in Taiwan solar cell, not only very difficult to obtain the land, how to maintain such a large area of solar cells is hard to imagine, therefore, the use of nuclear fusion reaction to produce the required energy, seems to be a most effective way of cleaning being the case Why can not develop nuclear fusion power is still out of it? The green laser pointer would be no longer within the quality guarantee range if the product is damaged on the way of sending for repair.Although the raw materials required for nuclear fusion - - deuterium element, you can get from the sea and completely unlimited supply, but fusion requires high-density conditions, with great kinetic energy react to the traditional way is to obtain high kinetic energy, and use of multiple collisions long enough to make up for the density and this method has some difficult problems to solve, first reaction of large quantities of radiation loss, the other is how the temperature such a high particle confined to a specific long-range control if the laser fusion power generation, there are many advantages. First, the effect can be achieved using kinetic energy to accelerate addition, you can use a powerful green laser led light pressure caused by compression of fuel, and fuel After the density, it can speed up the reaction. The green laser pointer would be no longer within the quality guarantee range if the product was damaged by being used in research and development.Finally, there is limited use of particle inertia to achieve the effect, so that the particle has not touched on the role of the reactor before the barrier is completed, a project called "HiPLER" (High Powered Laser Energy Research ).
