Development of femtosecond and attosecond laser
 We are developping ultra-short pulse laser. (femto-: 10-15, atto-: 10-18) If it irradiate an atom, electrons are vibrated directory, and monocycle x-ray pulse is emitted.
Coherent control of laser beam
 We are developping amplitude distribution, phase and polarization control of laser beam.
Fabrication of functional nanostructures by femtosecond laser processing
 Periodic superfine structures are fabricated by interfering femtosecond laser processing. These are useful for metamaterial,
