John Reid, Robert K Brimacombe, Edward S Williams: Purification of laser gases. Lumonics, December 17, 1991: US05073896 (18 worldwide citation)

Purification of the gas mixture used in an excimer laser is carried out by cooling such mixture in a cryogenic trap to a temperature that is low enough that the lasting gas or gases (e.g. krypton, xenon, fluorine, hydrogen chloride) and the impurities are all substantially fully condensed. This temp ...

An excimer laser system in which the expensive noble gases are reclaimed, while the halogen gas is sacrificed, and the impurities developed during operation of the excimer laser are removed. In the approach disclosed a multi-stage gas purifier is used with a single, premix gas bottle containing a ha ...

Glen Gallant, Edward S Williams, Robert W Weeks: Excimer laser. Lumonics, January 14, 1992: US05081638 (1 worldwide citation)

An excimer laser has a pair of main electrodes defining a lasing space, and a series of pairs of pre-ionization pins arranged alongside the main electrodes. These pins form preionization gaps for generating discharges that provide ultraviolet radiation to condition the gas in the lasing space. The i ...

The disclosure relates to the removal of hydrogen fluoride (HF) from an excimer laser either in operation or in standby using a metal halide salt reactor. Removal of HF is desirable because the contaminant not only absorbs laser emission, thus reducing laser power, but it is also chemically reactive ...

John H Hunter, Ian J Miller, Shane Boisclair, Edward S Williams, Chris Wimperis, Vaz Zastera: Virtual image phase array. LightMachinery, Teitelbaum Bouvetich & McLachlen, Neil Teitelbaum, December 25, 2018: US10162186

A virtual image phase array (VIPA) includes two parallel surfaces, a first highly-reflective surface with a highly-reflective coating, and a second partially-reflective surface. The first highly-reflective surface also requires an input zone with an anti-reflection coating, which abuts the highly-re ...
