  • Systems and methods for laser beam direct measurement and error budget
    Patent number: 10179070
    Abstract: Embodiments of the present invention generally describe systems, devices, and methods for directly measuring pulse profiles during pulse delivery. In some embodiment, the pulse profiles may be measured while the pulse is delivered to ablate a material. Embodiments, may calculate ablation spot parameters based on the pulse profiles and may refine one or more subsequent laser pulses based on deviations from the calculated ablation spot parameters from desired ablation spot parameters. In some embodiments, a fluence profiler is provided. The fluence profiler may measure a pulse profile of a laser pulse from a portion of the laser pulse. The fluence profiler may utilize a UV radiation energy sensor device and a camera-based imager. The measurements from the UV radiation energy sensor device and the camera-based imager may be combined and scaled to provide a measured pulse profile that corresponds to the delivered pulse.
