US patent 7,416,258- Methods of using a laser to spall and drill holes in rocks
Apparatus and methods of using lasers are provided for spalling and drilling holes into rocks. A rock removal process is provided that utilizes a combination of laser-induced thermal stress and laser induced superheated steam explosions just below the surface of the laser/rock interaction to spall the rock into small fragments that can then be easily removed by a purging flow. Single laser beams of given irradiance spall rock and create holes having diameter and depth approximately equal to the beam spot size. A group of the single laser beams are steered in a controllable manner by an electro-optic laser beam switch to locations on the surface of the rock, creating multiple overlapping spalled holes thereby removing a layer of rock of a desired diameter. Drilling of a deep hole is achieved by spalling consecutive layers with an intermittent feed motion of the laser head perpendicular to the rock surface.

- Lower-cost microchannel plates for sensing and imagingIntellectual Property Available to License
Technology
The invention is a method and system for fabricating micro-channel plate (MCP) detectors. An anodized aluminum oxide membrane is provided and includes a plurality of nanopores which have an Al coating and a thin layer of an emissive oxide material responsive to incident radiation, thereby providing a plurality of radiation sensitive channels for the micro-channel plate detector.
Benefits
By using atomic layer deposition to gain increased control, the invention allows cost-effective, larger-area MCP fabrication. Large-area, fast MCPs could have applications in research, industry, and medicine.
- Lower-cost, efficient fabrication of microchannel platesIntellectual Property Available to LicenseUS Patent 10403464B2
- Method of Making and Using 3D Printed Microchannel Plates
Technology
The invention provides a gain device having a plurality of channels with polygonal shape. The invention also provides a method for producing microchannel plates (MCPs) by of providing a pre-polymer; and directing a laser over the pre-polymer into a pre-determined pattern. This includes a method for efficiently 3D printing an object.
Benefits
Microchannel plates have applications in neutron and other detection. A need exists for cheaper and more widely available methods to manufacture larger-scale MCPs. This invention overcomes many of the disadvantages to current MPC manufacture.
