摘要： A method for enhancing photoreactive absorption in a specified volume element of a photoreactive composition. In one embodiment, the method includes: providing a photoreactive composition: providing a source of light (preferably, a pulsed laser) sufficient for simultaneous absorption of at least two photons by the photoreactive composition, the light source having a beam capable of being divided: dividing the light beam into a plurality of equal path length exposure beams: and focusing the exposure beams in a substantially non-counter propagating manner at a single volume element of the photoreactive composition simultaneously to react at least a portion of the photoreactive composition. In another embodiment, a method includes: providing a photoreactive composition capable of photoreactive absorption: and exposing the photoreactive composition to laser light from a plurality of substantially non-counter propagating directions simultaneously, wherein the light overlaps in time and space at a predetermined focus spot.

摘要： Methods of fabricating optical elements that are encapsulated in monolithic matrices. The present invention is based, at least in one aspect, upon the concept of using multiphoton, multi-step photocuring to fabricate encapsulated optical element(s) within a body of a photopolymerizable composition. Imagewise, multiphoton polymerization techniques are used to form the optical element. The body surrounding the optical element is also photohardened by blanket irradiation and/or thermal curing to help form an encapsulating structure. In addition, the composition also incorporates one or more other, non-diffusing binder components that may be thermosetting or thermoplastic. The end result is an encapsulated structure with good hardness, durability, dimensional stability, resilience, and toughness.
