<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a gas cell having a good optical window with excellent mass productivity, in which a dicing plane is made into a laser passing window, and a gas introducing path is provided as a metal holder. <P>SOLUTION: The method of manufacturing the gas cell includes: a step A of completing a processed glass substrate 20 projected a gas introducing cylinder 3 on the glass substrate 1; a step B of completing a processed glass substrate 21 having a rectangular second through-hole 5; a step C of completing a processed glass substrate 22 having a rectangular recess 7; a step D of forming a gas holding portion 9 for holding an alkali metal vapor in the glass substrate laminated body 23, filling rubidium (alkali metal) gas 8 from the opening 3a of the gas introducing cylinder 3 under an inert gas environment, sealing the opening 3a by welding, and dicing along a cutting line 25. As a result, a gas cell 26 having planes A to D are formed parallel to respective planes of the gas holding portion 9. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
