the laser tweezers move the blood cells a few micrometers in diameter

 For example, isolated from the blood of a single red blood cells sickle-shaped red blood cells for anemia or malaria therapy. Laser tweezers can "clip" live micro-particles, because the center of the laser beam intensity is greater than the edge strength, so when a tiny laser beam particles, the refraction of light from the center of light more than forward. When the refraction of light get out of momentum, the particle momentum on the reaction points to the laser beam on the center, so the particles are always attracted to the laser beam center. If the particles are very small and has very little gravity or friction, when the laser beam moves, the particles will move with it. However, the laser tweezers move the blood cells a few micrometers in diameter, but now want to move from 2 to 20 nm diameter carbon nanotubes will be much trouble. Therefore, the use of a single laser tweezers to move large amounts of carbon nanotubes to a certain location, may be the same trouble with an atomic force microscope.Quality Report of green laser pointer
green laser pointercan be controlled in groups. According to this type of selective photothermal effect of laser theory (ie, different wavelengths of laser selectively act on different colors of skin lesions), the instantaneous power of its powerful, highly focused radiation energy and the selective coloring, very short pulse wide, the role of the laser energy is concentrated in the pigment particles, the direct vaporization, crushed, removed from the body through the lymphatic tissue, without affecting the surrounding normal tissue, and its effective, safe and reliable, no scar, less pain and enjoys popular support. Laser cosmetic surgery pioneered a new era in medicine. Ultra-high-energy pulsed CO2 laser resurfacing skin surgery cosmetic surgery to open up a new technology. It uses high-energy, short pulse laser, the aging, damaged skin tissue to be vaporized instantly, without harming surrounding tissue, the treatment process is almost no bleeding, and precise control of the role of depth. The effect of the international medical community of plastic surgery full recognition, known as "creating a new era of medical cosmetic"; In addition, more high-energy ultra-pulsed CO2 laser treatment of bags under the eyes, snoring, and even laser whitening teeth, the efficacy of its safety precise, simple and efficient treatment in the medical field has created a miracle.
Laser weapons have attack speed, to flexible, enabling precision strike, immune to electromagnetic interference, etc., but there are also vulnerable to weather and environmental impact of weaknesses. Laser weapons more than 30 years of development history, the key technology breakthrough has been made in the United States, Russia, France, Israel and other countries have successfully undertaken a variety of laser-shooting test. The current low-energy laser weapons already in use, mainly for interference and blinding than the close of the photoelectric sensor, and attack the human eye, and some enhanced observation equipment; high-energy laser weapons, the main use of chemical lasers, in accordance with the current level, the next 5-- 10 years is expected to be deployed on the ground and air platforms used for tactical air defense, theater missile defense and anti-satellite warfare.
