The help of greenlaser pointer with remote control

This is the laser and laser physics from the exciton basis. In addition plasmon sub-surface laser is smaller than the depth of the sub-nano-plasmonic devices. Only produce nanoscale SPs. However, based on surface plasma polarization spectrum along the direction perpendicular to the surface normal. It is much larger than the wavelength spread of the length of the order. The researchers also reported a new stimulated emission mode. SPs in this mode is in a flat metal surface free transmission, and reflection does not have to go through to produce the lasing cavity. Exciton from abroad and other technology research and related applications. Pageup function ofgreen laser pointer has been successfully developed.
Domestic and international laser plasma physics research exciton status and progress. Laser physics from the main study exciton laser interaction with plasma exciton problem. This is a new rapidly changing area. Laser plasma physics research on the subject to a great extent the scope of the laser intensity, so its progress and advances in laser technology are inseparable. 1960 Mamain successfully developed the first ruby laser, so that mankind truly entered the era of the laser. Laser in its forty years of development history, has undergone several landmark changes in technology, every step to enhance the peak power three orders of magnitude. Ways to increase power without an external two ways: First, the same energy compressed into shorter and shorter pulse (the pulse width decreases); the second is for a specific pulse width to improve the energy value. Pagedown  function is the newly added feature ofgreen laser pointer.
First laser peak power in the kW range; 1962, Q-Technology will be shortened to nanosecond pulse width (ns), resulting MW pulse. In 1964, the mode-locking technology allows the pulse width down to picoseconds (ps) order of magnitude, the power to GW (focusing strength 1015W/cm2). GW pulse field strength is close to the atomic size of the electric field (109V/cm2), arising from the self-focusing and other nonlinear effects, will weaken the beam quality, and even cause damage to the amplifier components. Thus the subsequent 20 years, desktop laser output power standstill. In order to obtain high-power laser, the only way is to build large expensive laser. 1985 chirped pulse amplification (CPA) come out [6], pulsed power again leap. CPA is the first principle of pulse broadening, and then zoom in, and then compressed to an initial pulse width. The design of green laser pointer can be improved more.
This method is effective control of the amplification process of dispersion and nonlinear effects, thus ensuring the same magnification before and after the pulse, and energy to enhance the nine orders of magnitude, up to J from the order of magnitude nJ. Prior to GW kW pulse from the pulse compression amplification, the power to enhance the six orders of magnitude. CPA technology by 1000 times the pulse broadening, it can be further enlarged to the saturation level, its contribution to the pulse power pulse energy but will enhance the three orders of magnitude. With CPA, desktop laser output power to break through the bottleneck, which will be before the only major work on the laser back to university laboratories, the consequent opening up many new areas of research. CPA has also developed a theory based on the application in a large laser on optical parametric chirped pulse amplification (OPCPA). 1996 has been achieved PW (1015w) level pulses [7]. The design of green laser pointer is the focus of the technical meeting.
Along with the constant peak power laser desktop refresh, laser and plasma exciton interaction into the electronic era with relativistic velocity oscillations. If the optical as light - electron interactions of science, then dominated by the relativistic effects of light - the natural use of the relativistic optical electron interaction term. Since the advent of the laser, scientists have studied the system of bound electron nonlinear optics. Classical bound electron nonlinear optics, dealing with the case of electrons in the vicinity of the nucleus. Electronic displacement is small, the Lorentz force F (t) is proportional to the displacement x (t). The design of green laser pointer has been put forward in the meeting.
