  • Three -dimensional optical amplifier structure
    Publication number: 20050195474
    Abstract: The present invention relates to a multi-pass three-dimensional amplifier structure in which a beam of light traverses an amplifier medium multiple times via distinct multiple paths. The distribution of the multiple paths being such that the volume occupied by the multiple paths inside the amplifier medium substantially overlaps with the volume of the amplifier medium being optically pumped by an optical pump beam. The distribution of the optical paths is such that no more than two of the multiple paths lie in a same plane. The astigmatism induced by anisotropic amplifying crystals is self-compensated by aligning the crystallographic axes of the amplifying crystal at a 45° angle to the longitudinal axis of the redirecting means.
