The wavelength of green laser pointer contains 605nm

The wavelength of green laser pointer contains 605nm which

emits red laser beam.
Thus, in the case of long-pulse amplification, either high laser flux of high energy extraction efficiency, while maintaining a low enough power density in order to avoid nonlinear effects,

skillfully laser peak power increased by several orders of magnitude . Figure 1 Principles of the CPA technology and LLNL petawatt laser facility ? "Aurora 2" laser device in 2001 began to operate

in "Aurora 2" is a 20TW, 10Hz laser systems, high energy density physics experiments important tool. Currently located at the Institute of Physics, Chinese Academy of Sciences, Laboratory of

Optical intense laser high energy density physics research group. It is the super bright green laser pointer with key lock.
The aluminum of green laser pointer has the better heat dissipation
Wavelength: 800nm; single pulse energy: 5J; Contrast Ratio:> 109 Pulse Width: 30fs; peak power: 100TW; repetition frequency: 0.1Hz ? hot electron generation, transport and energy deposition in

ultra-intense laser plasma interaction will produce high energy electrons, ie, hot electrons. The hot electron generation and transmission is one of the important issues of laser high energy

density physics, is also a "fast ignition" key to the success of inertial confinement fusion. Hot electrons generated in the interaction part of the escape from the target before, part of the high

-density plasma and target transport. The hot electrons can stimulate a wide range of electromagnetic radiation (high-energy x-rays - terahertz), also have a strong electrostatic field. And at the

same time, the safety key lock design can avoid others using green laser pointer without permission.
The field the ions are accelerated to high energy. The following figure is the image of the physical processes described. The laser-driven ultrafast hard X-ray source synchrotron radiation source

proved to be of great scientific and applied value of the device. However, due to the vacuum speed limits and other restrictions, so that these devices are expensive, bulky, can not provide the

ultra-short time-resolved, and their use is subject to greater constraints; medical ray tube electron ray excitation process of separation The brightness and size is not conducive to improving the

resolution of imaging. The hard-ray source of the ultra-intense laser-driven electron and-ray excitation is synchronized with the region.
