In biology, the use of femtosecond laser technology are being provided by the difference absorption spectrum, the pump / probe techniques to study the photosynthetic reaction center of mass energy transfer with charge separation process. Ultrashort pulse laser is also used in information transmission, processing and storage areas. The first use of chirped pulse amplification terawatt laser desktop to achieve successful operation of began in 1988, this result indicates that in the laboratory super-and ultra-light femtosecond physics research began. Research in this area, because of the role of ultra-short laser field has been greatly exceeded the equivalent of electrons in atoms or limitations of field, perturbation theory can no longer set up to be the development of new theoretical treatment. The working instruction of green laser pointer includes the detailed warranty description.
In 1020W/cm2 of light intensity, can simulate astrophysical phenomena. 1019-1021W/cm2 ultra-high intense laser generated hot electrons (200keV <E <1MeV) ions can be triggered by heating a large number of nuclear fusion. This inertial confinement fusion (ICF) to ultimately achieve the fast ignition concept of national security and energy use will make an invaluable contribution. Femtosecond laser is another important application of micro-fine processing. Typically, according to the standards of the laser pulse duration is greater than 10 ps (equivalent to heat conduction time) laser pulses are long pulse, use it to process materials, due to thermal effect changes in the surrounding material, thus affecting the machining accuracy. The china laser pointer company decides to hold the ceremony.
The pulse width of only a few thousand trillionth of a second femtosecond laser pulses is a unique material processing characteristics, such as the processing aperture little or no melting zone; can achieve a variety of materials such as metals, semiconductors, even within the transparent material biological tissues such as micro-machining, engraving; processing area can be smaller than the focus size, breaking the diffraction limit, and so on. Some car manufacturers and heavy equipment factory is currently studying femtosecond laser processing with a better engine nozzle. Use of ultrashort pulse laser, can be played on a few hundred nanometers wide metal hole. Held recently in Orlando, Optical Society of America meeting, IBM's Haight said, IBM has a femtosecond laser system for large-scale integrated circuit chip lithography process. With femtosecond laser cutting, almost no heat transfer. FAQ of green laser pointer should be prepared for the customer.
Lawrence Livermore National Laboratory, U.S. researchers found that the laser beam can be safely cut high explosives. The laboratory Luo Sike said: "Femtosecond laser as a cold treatment promising tool for the dismantlement of decommissioned rockets, artillery shells and other weapons." Femtosecond laser can be used for cutting brittle polymer, without altering the its important biochemical properties. Biomedical experts have it as ultra-precision surgical blades, for vision correction surgery, both to reduce tissue damage and does not leave surgical complications, or even single cells moving on precision surgery or for gene therapy. There is now also studying how femtosecond laser for dental treatment. Some scientists have found that the use of ultrashort pulse laser to remove a small piece of tooth, without affecting the surrounding material. The director is mainly in charge of site management of green laser pointer .
U.S. Clark-MXR Corporation recently launched series of ultrafast laser micromachining UMW table represents this area is the most cutting-edge commercial femtosecond laser micromachining system, which includes the use of ultra-short pulse laser micromachining of all required equipment and accessories, can be used for micromachining of any materials, generate sub-micron fine structure, will not damage the surrounding material, will not cause material splash, extremely precise machining results and highly reproducible. We believe that with ultrashort pulse laser technology with high reliability and further development of commercial femtosecond lasers to further improve the femtosecond laser will be more widely in more fields of application. Optoelectronics Technology, North University of provincial Lab & Photonics and Photonic Technology Research Institute has carried out industrial high-power diode laser-pumped solid-state femtosecond laser research work. Workshop management of green laser pointer plays an important role in manufacturing green laser pointer .
