  • Patent number: 7893384
    Abstract: A laser material manipulation system is provided for material processing, such as laser ablation, laser deposition and laser machining. The system includes a laser for emitting laser pulses and a laser imaging device having an array of controllable imaging elements. The laser imaging device receives the laser pulses emitted from the laser, forms a laser image through the controllable imaging elements, and projects the laser image onto a target material which is to be processed. The projected laser image processes the material according to a desired pattern. The laser can be a femtosecond laser. The laser imaging device can be a liquid crystal display (LCD) or a digital micromirror device (DMD). An SEM can be used for monitoring the material distribution and dynamically adjust the laser image according to the monitor result.
