Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
67 words
A dye laser system comprising: a dye gain medium; means for resonating optical radiation in said gain medium; and means for optically pumping said gain medium, characterized in that; said means for optically pumping said gain medium includes a capillary flash tube containing an excimer gas mixture; means for generating an electrical lamp pulse; and means for capacitively coupling said lamp pulse through said excimer gas mixture.
Claim 2
Dependent Claim
67 words
A dye laser system comprising: a dye gain medium; means for resonating optical radiation in said gain medium; and means for optically pumping said gain medium, characterized in that; said means for optically pumping said gain medium includes a capillary flash tube containing an excimer gas mixture; means for generating an electrical lamp pulse; and means for capacitively coupling said lamp pulse through said excimer gas mixture.
Claim 3
Dependent Claim
60 words
A dye laser system according to claim 1, in which said means for capacitively coupling said lamp pulse includes an electrode having a reflective surface and being disposed along a first side of said flash tube opposite said gain medium for coupling electrical energy into said excimer gas mixture and directing light from said flash tube toward said gain medium.
Claim 4
Dependent Claim
54 words
A dye laser system according to claim 2, in which said excimer gas mixture is formed from at least two constituent gases that combine, under the influence of an electric discharge, to form an excimer that radiates in a band of less than 60 nanometers centered on a wavelength of less than 500 nanometers.
