Outline of Final Research Achievements

A new type of dielectric laser accelerating structure applied with laser material process ing was proposed. This method works on the mid infrared wavelength regime, and it has no material limitation. In this experiment, we realized that 4 different type of materials (silicon, sapphire, diamond, calcium fluoride) is formed to accelerating structure for the regime of mid infrared operation.
