The high power green laser pointer is very popular with astrophile
High-intensity laser can cause a number of nuclear reactions, when the laser intensity I> 10 18 W/cm2, the jitter in the laser electric field of electron energy to do 0.511MeV, produced a relativistic plasma, the use of intense laser produced plasmas End field to accelerate electrons, such as the use of a compact laser repetition rate of the electron can produce 200MeV. The high power green laser pointer is very popular with people who are interested in astronomy.This type of laser-plasma accelerator with electron accelerators are usually higher than 1000 times the acceleration gradient, that is to GV / m. use high-strength? single laser pulse also received 100MeV electron and measured its bremsstrahlung. ultrashort laser can also produce proton beams, and began to use these proton beams produced positron emission tomography (positron emission tomography, PET) needs short-lived positron sources, a small laser to generate the proton of the generator and the economy is expected in the future for proton cancer. the use of ultrashort laser is directly Rutherford Appleton Laboratory in the UK e-launched, they used the repetition frequency of TW-class laser, hit the target on the high-Z elements to be 2 × 107 per pulse in the positive electron, it is for very basic research and materials science applications. The high power 5mW laser pointer emits pretty green light.By ultrashort laser interaction and deuterium clusters, fusion reactions produce neutrons, which can reach yields of sub-105 neutrons / Joule, the energy efficiency of laser-produced neutrons have reached the world's largest laser level It can be a table of neutron sources, due to which high-throughput sub-pulses, but the total neutron dose is very small, suitable for in vivo neutron radiography of biological and materials science research. the use of ultrashort laser and deuterium the role of polyethylene produced neutrons. The high power 100mW laser pointer can be used for pointing out the location of stars at dark night.Hilsher and others with a titanium sapphire laser (300mJ, 50fs, 10Hz, 1018W/cm2) bombardment of deuterated polyethylene target to produce 104 neutrons / pulse. the use of ultrashort laser In the relativistic electron scattering on, resulting in hundreds of femtoseconds? tens of angstroms of hard X-rays, can be used to study the materials and life science issues, this ultra-fast hard X-ray source for the study of some high-Z material and time-resolved ultrafast phenomena is of great significance. ultrashort laser-produced high-energy electrons in the material produced in high energy X-rays, can cause fission in uranium fissile material and fission in the target number of fission products detected In the laser intensity reached 1028W/cm2 Blue Laser Pointer, the electric field strength than the Schwinger field only (vacuum breakdown field strength) one order of magnitude, in this field, due to vacuum fluctuations are excited, the laser it is possible to generate from the vacuum electron-positron pairs, the United States Lawrence Berkerly laboratory high-energy accelerator at SLAC, with 1018W/cm2 laser beam and focusing properties of the electron beam well 46.6GeV collide, resulting in more than 200 electron-positron. The high power 200mW Laser Pointer has been used for sending out weft at open field.This is due to collide in the reverse electron and laser in the coordinate system from the electronic point of view, the laser field enhancement of the Lorentz factor of times, so that can far exceed the Schwinger field value directly from the vacuum produce some electron pairs.
