  • Laser damage hardening of light modulator components for use with high optical fluence systems
    Patent number: 11656511
    Abstract: An apparatus with first and second transparent conductive oxide layers is described. A photoconductive layer can be positioned between the first and a second transparent conductive oxide layers. The photoconductive layer can be a crystalline layer that can include bismuth silicate or other suitable materials. An electro-optical layer is positioned in contact with the photoconductive layer. In some embodiments the photoconductive layer is positionable to receive a write beam that defines a two-dimensional spatial pattern.

  • Additive Manufacturing System For Object Creation From Powder Using A High Flux Laser For Two-Dimensional Printing
    Publication number: 20200189038
    Abstract: A method of additive manufacture is disclosed. The method can include providing an enclosure surrounding a powder bed and having an atmosphere including helium gas. A high flux laser beam is directed at a defined two dimensional region of the powder bed. Powder is melted and fused within the defined two dimensional region, with less than 50% by weight of the powder particles being displaced into any defined two dimensional region that shares an edge or corner with the defined two dimensional region where powder melting and fusing occurs.
