| Outline of Final Research Achievements |
The main purpose of this research is the generation of coherent low frequency radiation, such as THz light by using a periodically aligned micron-order plasma boxes, which are produced by the strong laser irradiation on a synthesized honeycomb film. We call this structured plasma as a "radiative plasma cell." This film is produced by a self-organized process. We have been developing a stable method to make the honeycomb film with an arbitrary period. As a result, we found the conditions to synthesize the film with a wide range periodicity.
On the other hand, we have conducted several simulation runs in order to find the conditions for the incident laser and the periodic target to optimize the emitted radiation intensity. In addition, we also calculate the asymmetrically aligned carbon nanotubes to generate a low frequency radiation more easily. This idea is verified by a computer simulation and this structure is expected to be a new target to generate a low frequency radiation.
