    Abstract: An M2 value beam profiling apparatus and method is described. The M2 value beam profiler comprises an optical axis defined by a focussing lens assembly and a detector, wherein the focussing lens acts to create an artificial waist within an optical field propagating along the optical axis. The beam profiler also comprises a multiple blade assembly having a first set of blades located at an artificial waist position and a second set of blades longitudinally separated along the optical axis from the artificial waist position. The multiple blade assembly therefore provides a means for selectively passing the blades through the location of the optical axis. Employing these measured widths allows for the M2 value of the optical field to be determined.

    Abstract: The present invention provides methods, systems, and apparatus for calibrating a laser ablation system, such as an excimer laser system for selectively ablating a cornea of a patient's eye. The invention also facilitates alignment of eye tracking cameras that measure a position of the eye during laser eye surgery. A calibration and alignment fixture for a scanning laser beam delivery system having eye tracking cameras may include a structure positionable in a treatment plane. The structure having a feature directing laser energy incident thereon to a calibration energy sensor, at least one reference-edge to determine a characteristic of the laser beam (shape, dimensions, etc.), and an artificial pupil to determine alignment of the eye tracking cameras with the laser system.

    Abstract: Systems and methods for measuring an intensity characteristic of a light beam are disclosed. The methods include directing the light beam into a prism assembly that includes a thin prism sandwiched by two transparent plates, and reflecting a portion of the light beam by total-internal-reflection surface to an integrating sphere while transmitting the remaining portion of the light beam through the two transparent plates to a beam dump.
