Abstract
An adaptive laser system (10) includes an adaptable laser (12), a waveform sensor (14), an amplitude distribution sensor (16), and a processor (18) for converting data from the sensors into commands for controlling the waveform of a laser beam. Amplitude distribution data is to weight waveform data as the processor determines actuator commands for deforming the laser's main mirror (22). Amplitude weighting permits more accurate determination of the waveform sensor-to-actuator-coupling matrix and more precise optimization of the on-axis intensity of the laser beam across the laser aperture.
