Paper Abstract

The SABLE experiment investigated the ability of phase-conjugate adaptive-optics to compensate strong thermal blooming and turbulence encountered during atmospheric propagation of a high-power laser beam. The experiments utilized a 10 kW hydrogen fluoride laser, selected because its spectrum is strongly absorbed by the atmosphere. Characteristics of the beam at both the transmitter and receiver, of the atmosphere along the propagation path, and of the adaptive optics were measured and recorded during the tests and used to test the accuracy of a time-dependent computer propagation code. Wind variations along the propagation path were shown to significantly improve system performance and to suppress the phase conjugate instability.
