  • Laser and laser-assisted free electron beam deposition apparatus and method
    Patent number: 5849371
    Abstract: A laser and laser-assisted multi-beam deposition apparatus for evaporating and/or sublimating a material to deposit on a substrate comprises using a laser and an electron beam, or two lasers, simultaneously applied to the material to vaporize the material with reduced ejection of material particulates and reduced oxidation of the material.
