DOE PAGES Journal Article: Repair of a Mirror Coating on a Large Optic for High Laser Damage Applications using Ion Milling and Over-Coating Methods.

Read On

When an optical coating is damaged, deposited incorrectly, or is otherwise unsuitable, the conventional method to restore the optic often entails repolishing the optic surface, which can incur a large cost and long lead time. We propose three alternative options to repolishing, including (i) burying the unsuitable coating under another optical coating, (ii) using ion milling …

InGaAsP/InP quantum well ridge waveguide lasers were fabricated for the evaluation of Ga+ focused ion beam milling of mirrors. Electrical and optical properties were investigated. A 7% increment in the threshold current, a 17% reduction in the external quantum efficiency, and a 15 nm blueshift in the emission spectrum were observed after milling as compared to the as …

Mechanical cutting, which includes tooling and machining, is a process that uses power-driven equipment to shape and form material into a predetermined design. Some common machines used in mechanical cutting include lathes, milling machines, and drill presses, which correspond to the processes of turning, milling, and drilling, respectively.

2.2. Ion Milling: Etch the Unsuitable Coating Completely from the Optic Surface with Ion Milling, and then Recoat the Optic. Ion milling is a physical etching process that involves the ionization of a gas (or combination of gases) that is accelerated by an ion source. 3 The ion source is typically directed at the surface to be etched, and the bombardment of the ions …
