Abstract: A multicore collimator collimates light signals transmitted by respective cores of a multicore fiber. An array of gradient-index lens includes a plurality of individual gradient- index lenses corresponding to respective cores of the multicore fiber. The plurality of gradient-index lenses extends through a lens array body between an input end and an output end thereof and has a lens-to-lens spacing that is larger than the core-to-core spacing of the multicore fiber. A taper at the input end of the array of gradient-index lenses provides a tapered transition between the core-to-core spacing of the multicore fiber and the lens-to-lens spacing of the array of gradient-index lenses. The array of gradient-index lenses is configured to collimate the light signals outputs from the coupler, and to provide the collimated light signals as an output at the output end of the array of gradient-index lenses.

Abstract: One optical system comprises a first optical surface, a faceted second optical surface, and a faceted third optical surface. The optical system is operative to convert a first bundle of rays that is continuous in phase space outside the first optical surface into a second bundle of rays that is continuous in phase space outside the third optical surface. Between the second and third optical surfaces the rays making up the first and second bundles form discrete sub-bundles each passing from a facet of the second optical surface to a facet of the third optical surface. The sub-bundles do not form a continuous bundle in a phase space that has dimensions representing the position and angle at which rays cross a surface transverse to the bundle of rays.

Abstract: A laser diode illuminator device and a method for optically conditioning the output beam radiated from such a device, so that highly-demanding illumination application requirements that call for high output powers within a specified field of illumination can be addressed. At the heart of the device is a two-dimensional stack of laser diode bars wherein the linear array of beamlets radiated by each laser diode bar is optically conditioned through its passage in a refractive-type micro-optics device followed by a cylindrical microlens. The micro-optics device performs collimation of the linear array of beamlets along the fast axis of the bars, and it also acts as a beam symmetrization device by interchanging the divergences of the laser beamlets along the fast and slow axes. The cylindrical microlens is for collimation of the beamlets along the slow axis. The optical conditioning is performed individually for each linear array of beamlets so that the radiance or brightness of the laser diode illuminator can be optimized while any specified field of illumination can be filled with an excellent uniformity of the radiant intensity.

Abstract: A system for focusing a light beam may be used for multi-photon stereolithography. It comprises a collimator or expander for adjusting the beam divergence and a scanner for directing the beam onto a focusing device to focus the beam to a focal point or beam waist and to scan the focused beam. A controller controls adjustment of the beam divergence so that the focal point or beam waist is scanned substantially in a plane. A light source may be provided to generate the light beam. The expander may comprise a diverging lens and a converging lens for expanding the beam to produce a collimated beam. The divergence of the collimated beam is dependent on the distance between the diverging lens and the converging lens, which may be adjusted to adjust the beam divergence. The focusing device may comprise a dry objective lens to focus the collimated beam onto the target material to induce multi-photon absorption in the target material at the beam waist of the focused beam.
