We predict accurate correction of thermal blooming by phase conjugation, for the case of a nonunity-magnitude reflection coefficient, over a wide range of easily realized experimental conditions. Diffusion relaxes a thermal grating that would otherwise spoil phase-conjugate correction. Phase conjugation is predicted to correct thermal blooming caused by continuous-wave lasers, collimated or loosely focused lasers, pulsed lasers blooming in gases, and broadband lasers.
