Abstract
Each of an optical component, a laser apparatus that includes the optical component and a method for operating the laser apparatus uses a particular reflective material layer located and formed over a substrate at a particular thickness for providing the optical component, the laser apparatus and the method for operating the laser apparatus with sufficient imperviousness to laser filaments under particular energy density fluence considerations. A particular reflective material layer comprises gold or a gold alloy. Other reflective materials may include silver, copper, aluminum and palladium reflective materials and related alloys.
Claims20
An optical component comprising:
- a substrate;
- and
- a reflective material layer located over the substrate, where the reflective material layer reflects a laser filament and is not damaged when impinged by the laser filament at a pulse energy at least about 10 mJ, an irradiance at least about 10e13 W/cm2 and a fluence at least about 0.62 J/cm2.
A laser apparatus comprising:
- a lasing component that provides a laser filament having a pulse energy at least about 10 mJ, an irradiance at least about 10e13 W/cm2 and a fluence at least about 0.62 J/cm2;
- and
- a reflective component upon which is incident the laser filament, the reflective component comprising a substrate and a reflective material layer that is not damaged by the laser filament.
A method for operating a laser apparatus comprising:
- providing a laser apparatus comprising:
- a lasing component that provides a laser filament having a pulse energy at least about 10 mJ, an irradiance at least about 10e13 W/cm2 and a fluence at least about 0.62 J/cm2;
- and
- a reflective component comprising a substrate and a reflective material layer selected from the group consisting of gold, silver, copper, aluminum, palladium and alloys thereof formed over the substrate;
- and
- energizing the lasing component to provide the laser filament that impinges upon the reflective component.
