Control system for ablating high-density array of vias or indentation in surface of object

A control system for controlling operation of a laser and controlling relative X-axis and Y-axis movement of the laser with respect to a product to be imaged to facilitate one of burning, drilling and forming a desired formation in a surface of the object to be imaged, the laser arranged to supply a collimated laser beam to a desired location along a rear surface of a mask and the mask altering the laser beam and emitting the altered laser beam, from a front surface thereof, directly at the product to be imaged without a lens located between the mask and the product to be imaged and without any adjusting movement of the mask relative to the product to be imaged, and the control system comprising:

• means for obtaining drill position data from a data storage device;
• means for sending necessary signals, derived from the obtained drill position data, to alter simultaneously a path of the laser beam emitted by the laser relative to the object to be imaged;
• means for providing a feedback to indicate that the path of the laser beam, from the laser to the product to be imaged, is suitably altered;
• and
• means for firing the collimated laser beam through the focusing member directly at the mask and emitting the altered laser beam, from the front surface of the mask, directly at the product to be imaged without a lens located between the mask and the product to be imaged and without any relative Z-axis movement between the mask of the product to be imaged for one of burning, drilling and forming the desired formation in the surface of the object to be imaged;
• and
• means for allowing the control system to access again the data storage device, following completion of the laser beam one of burning, drilling and forming the desired formation in the surface of the object to be imaged, to facilitate reading additional drill position data from the data storage device.

• a laser for generating an outputting a coherent light beam;
• X-axis and Y-axis automatic repeat positioners for redirecting a path of the coherent light beam supplied by the laser;
• a focusing member for receiving the redirected light from the X-axis and Y-axis repeat positioners and focusing the coherent light beam at least a desired one of a plurality of holographic imaging segments forming a holographic Imaging lens, and each one of the holographic imaging segments designed to alter the supplied laser beam and emit the altered laser beam, from a front surface thereof, directly at the product to be imaged without a lens located between the holographic imaging segments and the product to be imaged, and a spacing of the holographic imaging segments from the product to be imaged, along a Z-axis, being a fixed distance, and the control system comprising:
