  • Patent number: 9851570
    Abstract: An optical output coupler includes an uncoated plano-concave lens having a planar side and a concave side. An optical axis of the plano-concave lens is tilted at or near a Brewster angle relative to a beam axis. A first optical element is configured to focus a beam of radiation emerging from the planar side of the plano-concave lens along a first axis that is perpendicular to the beam axis. The first optical element is disposed between the planar side of the plano-concave lens and a second optical element. The second optical element is configured to focus a beam of radiation emerging from the planar side of the plano-concave lens along a second axis that is perpendicular to the beam axis, wherein the second axis is different from the first axis.
