A concave mirror using a pulsed quadrupole magnetic field has been demonstrated for cold atoms. Cold 87Rb atoms in the Zeeman sublevel F=2, M=2 have been reflected twice. The atomic cloud is refocused at every reflection with a ratio close to one. The transverse focusing is observed many times with a shorter period.
