Intense Terahertz Synchrotron Radiation by Laser Bunch Slicing at UVSOR-II Electron Storage Ring

概要

• 論文の詳細を見る

• A laser bunch slicing system has been constructed at the UVSOR-II electron storage ring to produce a submillimeter-sized microstructure on an electron bunch. As its first result, terahertz coherent synchrotron radiation (THz CSR) was successfully produced by the dense structure of the electron bunch. Its intensity is higher by four or five orders of magnitude than that of normal synchrotron radiation. The intensity is proportional to the square of the peak current of the electron bunch, as expected for coherent emission. It is also demonstrated that the spectral shape of the THz CSR can be controlled by changing the slicing laser pulse duration.
