The battery can be taken out of Laser Pointer

The battery can be taken out of Laser Pointer when it is not used.
Laser technology is related to the optical, mechanical, electrical, materials, and testing and many other subjects of an integrated technology, the traditional point of view, the scope of its research can be divided into: laser processing system. Including lasers, optical systems, machine tools, control system and detection system. Laser processing technology. Including cutting, welding, surface treatment, drilling, marking, scribing, trimming, and other processes. Laser welding: auto body thickness of the plate, auto parts, lithium batteries, pacemakers, relays and other sealing devices and sealing of various pollution and does not allow welding deformation device. YAG lasers are currently used lasers, CO2 lasers and diode-pumped lasers.
This laser was first launched in 1996. Martinez said he hoped his project to break the record in 2008, that is, the laser power of 1.3 to 1.5 Piwa Piwa between. Super Laser Project Leader McAlpine ? Martinez said: "We can make materials into an extreme state, this state on earth can not see and we intend to observe the phenomenon in Texas into space is equivalent to observing a exploding star. "Recently, scientists have developed a laser" seize "the new carbon nanotube technology and make it move. This technology can provide a chip manufacturing engineers to move to a predetermined position of nano-components of the new methods to create nanotube-based micro-chip. The charger of the rechargeable battery of Laser Pointer will be delivered together.
Only a few nanometers in diameter, about 100 nm carbon nanotubes with semiconductor properties, which means that carbon nanotubes could one day become a low-power ultra-fast computer chip basis. So far, the only way is to install carbon nanotubes using atomic force microscope called the expensive equipment, try to push the nanotube to the desired location, but this method is extremely cumbersome to manipulate. The charger of battery of Laser Pointer can be bought easily in the ordinary store.
To change this situation, the United States, Illinois, New York University and an optical company of scientists, researchers tested a product called "optical trap" technology, trying to be more convenient to manipulate carbon nanotubes. Optical technology is the use of laser capture can capture tiny particles the ability to move the laser beam in the laser to follow the movement of tiny particles. Because the laser can capture tiny particles, so it will be like when the forceps move as "folder" with tiny particles move. Scientists call this phenomenon is called "laser tweezers." Now biologists have been able to laser tweezers to grip the individual cells. The continuous operating time of Laser Pointer can be as long as 12 hours.
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.
