<p>A metallic gas cell (20) including a metallic casing (24) having an input open end (26) and an output open end (28), and a opening (30) located therebetween. The metallic gas cell also includes an input (30) and an output (34) optical modules, each being respectively hermetically attached to one of the corresponding open ends. Each of the optical modules is sealed in one of the corresponding open ends, thereby defining an airtight cavity in the casing when the opening is sealed. An optical energy absorbing gas is enclosed within the cavity. The metallic gas cell is advantageously modular for allowing the use of various input or output modules such as windows, lenses, lasers, photodetectors, and fiber collimators. The gas cell also allow multi-cavity gas cell that that use a minimum number of components and cells to be obtained. The present gas cell prevents alignment issues. There is also provided a method for manufacturing such a metallic gas cell.</p> |
