All components, for example, the famous femtosecond laser system manufacturers, Clark-MXR company will produce high-power femtosecond pulses all integrated into one box, the use of erbium-doped fiber femtosecond laser as seed source, with no need to adjust (NO the Tweak ) is specially designed to form a unique, ultra stable, ultra-compact CPA2000 Series Titanium Gem chirped pulse amplification system. , This system does not require the commercialization of femtosecond operation, can be widely used in many fields of scientific research and industrial. Ultrashort femtosecond laser and super features, in general, the field of applied research into the study of ultrafast transient phenomena and powerful phenomenon. green laser pointer includes the presentation, museum, inspection and so on.
They are allowed for a thorough and development with the shortening of the laser pulse width and pulse energy increases. The most direct application of femtosecond laser pulses is that people use it as a light source to form a variety of time-resolved spectroscopy and pump / probe technology. Its development is directly contributing to the physical, chemical, biological, materials and information science research into the microscopic field of ultrafast processes, and creating a new field of study, such as femtosecond chemistry, quantum control of chemical, semiconductor coherent spectroscopy. The combination of femtosecond laser pulses with nano-microscopy, so that people can study the carrier dynamics in semiconductor nanostructures (quantum wires and quantum dots and nanocrystals). laser pointer is definitely the good assistant and partner for the lecturer, teacher, tour guide, stargazer and explorer and so on.
In biology, people are taking advantage of differences in absorption spectra of the femtosecond laser technology, the pump / probe technology, the study of photosynthetic reaction center energy transfer, transfer and charge separation processes. Ultrashort pulse laser was also used in information transmission, processing and storage. The first successful operation of the use of chirped pulse amplification technology for desktop terawatt laser began in 1988, this achievement marks the beginning of the Femtosecond super-and ultra-light physics research in the laboratory. Research in this area, the role of ultra-short laser field is equal to or greatly exceed the limitations of field of the electrons in atoms, perturbation theory can not be established, the new theory to be developed. Technical specifications of green laser is in the following.
1020W/cm2 light intensity, we can simulate astrophysical phenomena. 1019-1021W/cm2 ultra-high intense laser generated hot electrons (200keV <E <1MeV) can be heated to the large number of ions caused by nuclear fusion. This inertial confinement fusion (ICF), the concept of fast ignition and ultimately for the national security and energy use to make an invaluable contribution. Another important application of femtosecond laser micro-fine processing. Typically, according to the standards of the laser pulse duration is greater than 10 ps (equivalent to the heat conduction time) laser pulse is a long pulse to processing materials, the surrounding material changes due to thermal effects, thus affecting the machining accuracy. Laser beam color of usa green laser pointer is green.
And pulse width of femtosecond laser pulses of only a few thousand trillionth of a second with a unique material processing characteristics, such as the melting zone of the processing aperture is little or no; can achieve a variety of materials such as metals, semiconductors, and transparent materials even within the biological tissues, such as micro-machining, engraving; machining area can be less than the focus size, to break through the diffraction limit. The car manufacturing plant, and heavy equipment, processing plant is currently studying better with femtosecond laser processing engine nozzle. Ultrashort pulse laser, can play a few hundred nanometers wide holes on the metal. Optical Society of America meeting held recently in Orlando, IBM's Haight said. Laser beam range of green laser pointer is less than 15 miles.
