| Research Abstract |
We have developed a novel technique to produce coherent synchrotron radiation by creating micro-density structure on high energy electron beam using laser. We have found that the transverse motion of the electrons play an important role for the efficiency of the coherent radiation. In the vacuum ultra-violet range, we have observed a saturation and oscillation of the output power in the high laser power range. We could explain this phenomenon as the result of the micro-bunching process in the over-bunching regime. These results are important in optimizing the input laser power for highly efficient coherent radiation generation.
