Abstract: A laser system calibration method and system are provided. In some methods, a calibration plate may be used to calibrate a video camera of the laser system. The video camera pixel locations may be mapped to the physical space. A xy-scan device of the laser system may be calibrated by defining control parameters for actuating components of the xy-scan device to scan a beam to a series of locations. Optionally, the beam may be scanned to a series of locations on a fluorescent plate. The video camera may be used to capture reflected light from the fluorescent plate. The xy-scan device may then be calibrated by mapping the xy-scan device control parameters to physical locations. A desired z-depth focus may be determined by defining control parameters for focusing a beam to different depths. The video camera or a confocal detector may be used to detect the scanned depths.

Abstract: The amount of energy to provide optical breakdown can be determined based on mapped optical breakdown thresholds of the treatment volume, and the laser energy can be adjusted in response to the mapped breakdown thresholds. The mapping of threshold energies can be combined with depth and lateral calibration in order to determine the location of optical breakdown along the laser beam path for an amount of energy determined based on the mapping. The mapping can be used with look up tables to determine mapped locations from one reference system to another reference system.
