Electron-beam focusing by the dipole force of an ultrashort laser pulse
The possibility of using the dipole force of the spatially nonuniform field of the ôåí*! mode (a hollow Gaussian beam) of an ultrashort-pulse laser to focus a low-energy electron beam into a region 10-100 A in size is analyzed. This effect might be utilized to develop an electron scanning microscopy which would employ low-energy electrons and which would be sensitive to the atomic and molecular structure of surfaces. © 1995 American Institute of Physics.
