The possibility of using the dipole force of the spatially nonuniform
field of the TEM(01) mode (a hollow Gaussian beam) of an ultrashort-p
ulse laser to focus a low-energy electron beam into a region 10-100 An
gstrom in size is analyzed. This effect might be utilized to develop a
n electron scanning microscopy which would employ low-energy electrons
and which would be sensitive to the atomic and molecular structure of
surfaces. (C) 1995 American Institute of Physics.
