Abstract
Laser-induced thermal blooming has been corrected with limited accuracy using deformabte mirrors.1,2 Recently, optical phase conjugation was suggested for thermal blooming compensation. However, it was predicted that 100% reflectivity would be a necessary condition for accurate blooming compensation by a phase conjugate mirror.3 Here we present experimental data showing accurate thermal blooming correction by stimulated Brillouin scattering (SBS) with 35-65% reflectivity and four-wave mixing (FWM) with 0.004% reflectivity.
