Demonstration of spontaneous thermal-blooming phase-compensation instability.
We have observed significant growth of phase modulation when thermal blooming is compensated by a 241-channel phase-conjugate adaptive-optics system. These modulations, which were not artificially seeded, occurred at a spatial frequency characteristic of the adaptive-optics system and resulted in a corresponding decay of the far-field irradiance. These experiments represent, to our knowledge, the first observations of a spontaneous phase-compensation instability.
