The invention discloses laser-array pore molding devices and a method. The steps of the invention includes that, firstly, pore diameter, pore distance and caliber parameter of a pore plate are set, and a processing file is produced, secondly, laser power, pulse width, pulse repetition frequency and pulse count are set, thirdly, the parameter of light beam location scanning is set, fourthly, work-pieces are located, a visual system is located, and vacuum negative pressure absorbs a probe guide plate, fifthly, pressure and flow capacity of opening assistant gas are set, the processing is started, finally, the pore diameter, the pore distance and the caliber parameter are measured after the finishing of the processing. The laser-array pore molding devices include an ultraviolet solid laser with high repetition rate and ultrashort pulse, a laser beam generator, a collimation beam-expanding device, a shutter, a light beam location scanning device, a CCD visual location system, an XYZ displacement working platform, and a vacuum negative pressure absorbing-sheet frame. The invention has the advantages that the disadvantages of low efficiency, easy damage of a 'punch', changeable pore diameter and the like which exit in the present mechanical punching manner are overcome, dynamic digital hologram is directly pressed on the surface of the material of noble metal commemorative coins, thereby ensuring the esthetics of the commemorative coins.
