Claim Text:
1. A self-seeding high power laser comprising: a spatial filter; an optical relay for circulating a low power un-distorted optical beam from the spatial filter, an adaptive optic optically coupled to an output of the optical relay for adaptively modifying a phasefront of the low power un-distorted optical beam; a high power amplifier optically coupled to an output of the adaptive optic phase control element for generating a high power un-distorted optical beam, wherein the adaptively modified phasefront injected by the adaptive optic cancels distortions produced by the high power amplifier to generate said high power un-distorted optical beam; a beamsplitter optically coupled to the high power amplifier for splitting the high power un-distorted optical beam into a high power output beam as the output of the self-seeding high power laser, and the low power beam; a focusing lens for focusing the low power beam into the spatial filter; a detector for detecting a metric of the low power beam filtered by the spatial filter; and a controller for inputting the detected metric and, based on the detected metric, adaptively controlling the adaptive optic to maximize the power of the high power amplifier.
