[5][6], Finding materials that stimulate emission was needed for the development of the SASER. In this active medium, a stimulated emission of phonons leads to amplification of the sound waves, resulting in a sound beam coming out of the device. Dolmens in Montana is page one of a four page series.Page two is Megaliths in Montana which is research, photos and comparisons with other megalithic sites around the world. This process can be stimulated by other phonons and then give rise to an acoustic amplification. SASER's central idea is based on sound waves. [citation needed], SASERs could have wide applications. [1] It focuses sound waves in a way that they can serve as accurate and high-speed carriers of information in many kinds of applications—similar to uses of laser light. These level spacings are continuously tunable by a significant adjustment of optical coupling. The number of photons of this coherent laser beam increases and competes the number of photons perished due to losses. 10 Million+ Stone Circles of South Africa. The set-up needed for the implement of sound amplification by stimulated emission of radiation is similar to an oscillator. The electrons release energy in any random direction and at any time (after their excitation). The similarity of this with the Free-electron laser is useful to understand the theoretical concepts of the scheme. Sound amplification according to the experiment taken in the University of Nottingham could be based on an induced cascade of electrons in semiconductor superlattices. Such levels can be formed by conduction and valence bands in narrow gap indirect semiconductors. [25] Since the entire system is electro-neutral, the process of pumping creates electrons and holes with the same rate. Sound Technology. The aim here is to check if the operation of this scheme with a rather moderate pumping rate can hold against the fact that excitons in coupled quantum wells have low dimensionality in comparison to phonons. 30 acres. In the superlattice, a new set of selection rules is composed that affects the flow-conditions of charges through the structure. According to an example of an electrically pumped SASER,[18] the active medium is confined between two planes, which are defined by the solid walls of the resonator. As the electrons hop between gallium arsenide quantum wells in the superlattice they emit phonons. In the United States, the Pentagon, DARPA, the Air Force Research Laboratory, United States Army Armament Research … Consequently, the pumping of these transitions has to be very intense so as to obtain a steady laser generation. The energy levels of electrons are confined in the superlattice layers. A mathematical analysis, leads to an equation for the average number of electron-hole pairs per one phonon mode per unit volume. A superlattice can consist of multiple ultra-thin lattices of two different semiconductors. This is the last hour of a 4 hour presentation in which he goes into the new science of sound, resonance, magnetism and SASER technology – Michael presents the mysterious cone shaped and torus tools which were used by the ancient civilisations to achieve unimaginable things – beyond the comprehension of most in the 21st century – who live under the false illusion that we are pinnacle of evolution and technology. One group from the University of Nottingham consisted of A.J. Call to ceremony at the Feather Pipe Ranch. This results to the assumption that the effective pump wave acting on the bubbles does not depend on the spatial coordinates. Then, one phonon going in, produces two phonons coming out of the superlattice. An electron does not stay in an excited state for too long. Ancient Levitation / Sound Levitation. In indirect exciton, electrons and holes are in different quantum wells, in contrast with direct exciton where electrons and holes are located in the same well. A relevant suggested scheme of sound amplification by stimulated emission of radiation using gas bubbles as the active medium was introduced around 1995[20] The pumping is created by mechanical oscillations of a cylindrical resonator and the phase bunching of bubbles is realized by acoustic radiation forces. Such values approach the electric puncture intensity of liquid dielectrics. This parallelism implies that lasers should be as feasible with sound as they are with light. They both can be thought of in terms of waves, and they both come in quantum mechanical units.
