We report that a deep ultraviolet (DUV)laser from the sixth harmonic of a 1064nm laser has been firstly used as light source in an ultrahigh energy-resolution angle-resolved photoemission spectroscopy(ARPES).The wavelength is 177.3nm obtained by using the second harmonic KBe2BO3F2 crystal with a frequency tripled 1064nm Nd:YVO4 laser.The large flux(1014-1015 photons/s)and narrow line width (0.26meV)are suitable for the ultrahigh-energy resolution ARPEs.The laser-ARPES can be a powerful tool to study the electronic structure at and near the Fermi level of the superconductor and correlated materials,The laser-ARPES has worked more than 500h already.
