ABSTRACT:
A device for producing phase conjugation of electromagnetic radiation using stimulated Brillouin scattering (SBS), comprising an SBS cell having a liquid perfluorocarbon as an SBS medium. The liquid perfluorocarbon is selected from the group of compounds having the formula C.sub.x F.sub.y, wherein x>1 and y>4. Preferably, x>4 and y<16, and most preferably, 4<x<7 and 6<y<15. Also, a solid state laser comprising the device. Also, a method for reducing the aberrations in a laser beam, such as aberrations created when the beam passes through an amplifying medium comprising the step of generating phase conjugation by SBS using a liquid perfluorocarbon as an SBS medium. Further, a method of producing an output laser beam comprising the steps of, generating an initial laser beam using a laser and phase conjugating the initial laser beam by SBS using a liquid perfluorocarbon medium as an SBS medium. The liquid perfluorocarbon is selected from the group of compounds having the formula C.sub.x F.sub.y, wherein x>1 and y>4. Preferably, x>4 and y<16, and most preferably, 4<x<7 and 6<y<15.
