Phase conjugation at 193 nm.
We have measured phase-conjugate reflectivities of 11% at 193 nm by using stimulated Brillouin scattering of ArF laser radiation from 2,2,2-trifluoroethanol (CF(3)CH(2)OH). This mirror has been shown to correct for the aberrations induced on the wave front by an ArF amplifier.
