Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 83 words
A method of insuring triggering of a laser flashlamp by application of an electrical impulse to an elongated metal strip permanently affixed to the outer surface of the quartz envelope of said flashlamp, comprising the steps of forming said metal strip by masking said flashlamp envelope to leave exposed an elongated region of said envelope, ion plating onto said exposed region of said envelope a thing layer of silver, and ion plating onto said plated layer of silver a thin layer of nickel.
Claim 2
Independent Claim 83 words
A method of insuring triggering of a laser flashlamp by application of an electrical impulse to an elongated metal strip permanently affixed to the outer surface of the quartz envelope of said flashlamp, comprising the steps of forming said metal strip by masking said flashlamp envelope to leave exposed an elongated region of said envelope, ion plating onto said exposed region of said envelope a thing layer of silver, and ion plating onto said plated layer of silver a thin layer of nickel.
Claim 3
Dependent Claim 19 words
The method of claim 1 wherein each of said layers has a thickness of at least 5000 Angstrom units.
Claim 4
Dependent Claim 59 words
The method of claim 1 wherein said ion plating steps include evaporating said layer material in a partially evacuated enclosure, ionizing said evaporated material in an inert gas plasma created by high voltage discharge into said gas and accelerating said ionized material to said flashlamp by the high voltage created within said enclosure between said flashlamp and said enclosure.
