Four Austrian physicists managed to develop the experimental scheme in which the single atom becomes one of resonator Fabri mirrors – the Feather.
The design of usual resonator Fabri – the Feather, consists of two mirrors, the main thing that these mirrors were parallel among themselves. It is necessary that in mezhduzerkalnom space passed a laser beam. At each reflexion of a beam, its some part will be uterivatsja because it will come to light. In the given experiment, the distance which overcomes light in a cavity, is not multiple to length of a wave of light. But if this parametre to change, in a pre-production model it is possible to observe the phenomenon of a constructive interference well and it is natural propuskanie, also will be maximum. But in case of change of size of an interval, the destructive interference which to appear in that case, will lead to falling of level of carrying capacity. Proceeding from it, it is possible to draw a conclusion that parametres of passage of radiation, are in direct dependence on distance between mirrors.
In the course of carrying out of new experiment, the role of one of mirrors was played by an ion of Barium Ba + which has been placed in a trap of Paulja. For the purpose of accurate keeping of distance between mirrors, the ion has been cooled by means of laser use on doplerovskoj to a technique. After the atom has been cooled, he did not leave more than on 20 Nanometers from the trap centre.
Then towards the resonator the weak laser radiation having length of a wave of 493 Nanometers which completely corresponds to transition 6S1/2—6P1/2 in barii has been directed. After the detailed analysis of results of research, it has been established that the share of the radiation passing through the resonator, will approximately change on 6 %. It is necessary to underline that similar resonators give more essential variations of carrying capacity, but the assumption that an ion in a status to carry out the same functions as a mirror – have been experimentally confirmed.
Authors of research consider that the similar technique will give the chance creations of optical switches on the basis of ions.
