A closed-loop system for phase compensation of thermal blooming has been designed and tested. This system-called CLASP for closed-loop adaptive single parameter-is a single-mode outgoing-wave dither system. CLASP has demonstrated stable convergence to the optimum thermal-blooming-correction amplitude in a laboratory experiment.
