    Abstract: Monolithic beam-shaping optical systems and methods are disclosed for an optical coherence tomography (OCT) probe that includes a transparent cylindrical housing having asymmetric optical power. The system includes a transparent monolithic body (110) having a folded optical axis and at least one alignment feature (that supports the end of an optical fiber adjacent an angled planar end wall (160). The monolithic body also includes a total-internal reflection surface (170) and a lens surface (204) that define object and image planes. Light from the optical fiber end traverses the optical path, which includes the cylindrical housing residing between the lens surface and the image plane. Either the lens surface by itself or the lens surface and the reflective (eg, TIR) surface in combination are configured to substantially correct for the asymmetric optical power of the cylindrical housing, thereby forming a substantially rotationally symmetric image spot (380) at the image plan e (IMP).

    Abstract: A folded laser system comprising: a coherent light source (20); a reflector (50); a lens I component (30) situated between the light source and the reflector; and a non-linear optical crystal (70), wherein the light source and the non-linear optical crystal are separated by a distance d>50 μm The lens component is positioned to provide a collimated beam when intercepting light from the light source, such that the collimated beam is at an angle to the optical axis of the lens, the reflector is situated to intercept the collimated beam and to reflect the collimated beam to the non-linear optical crystal through the lens; and the lens component is structured to provide an image on the non-linear optical crystal.
