Abstract: An ophthalmic laser ablation system is described with various optional features, some especially suitable for non-penetrating filtration on an eye. In one example, focusing of an ablation laser uses a movable lens coupled to a pair of converging light sources, which converge at the focal distance of the lens. In another example, laser ablation settings are selected for optimal ablation and minimal amount of thermal damage of a layer of percolating scleral tissue.

Abstract: Single-core and multi-core microcapsules are provided, having multiple shells, at least one of which is formed of a complex a coacervate of two components of shell materials. The complex coacervate may be the same or different for each shell. Also provided are methods for making the microcapsules.

Abstract: Reconditioning a fiber for laser applications by cleaving off its tip and shaping the cleaved end into a conical or pyramidal shape with a grinder. The cleaved end is grasped in a fiber holder. The grinder is driven, e.g., to rotate. The fiber holder is moved relative to the grinder to bring it into contact with the moving grinder. The fiber holder may be rotated during the contact. Preferably, the axis of symmetry of the fiber is substantially parallel to the plane of rotation of the grinder to effect tangential grinding.

Abstract: Under photoluminescence (PL) excitation, the lateral spreading of photo-excited carriers can suppress the photoluminescence signal from double heterostructure (DH) wafers containing a p-n junction. In any DH with a p-n junction in the active layer, PL is suppressed if the power of the excitation source does not exceed a threshold value. This effect can be advantageously used for a nondestructive optical determination of the top cladding layer sheet conductance as well as p-n junction misplacement, important parameters for injection lasers and LEDs.
