1. A method for calibrating laser pulses from a laser eye surgery system, the laser eye surgery system having an image capture device oriented for imaging an eye during laser eye surgery of the eye, the method comprising: imaging a known object with the image capture device of the laser eye surgery system, the imaged object having an imaged object size, an imaged object shape, and an imaged object location; directing a pulsed laser beam of the laser eye surgery system onto a calibration surface so as to leave a mark on the calibration surface; imaging the mark on the calibration surface with the image capture device of the laser eye surgery system, the imaged mark having an imaged mark size, an imaged mark shape, and an imaged mark location; and calibrating a laser beam cross-sectional shape, a laser beam cross-sectional location, and/or a laser beam cross-sectional size of the laser eye surgery system by comparing the image of the mark on the calibration surface to the image of the known object.
