RESEARCH ON GASEOUS OPTICAL MASER TO DEVELOP HIGH CONTINUOUS WAVE POWER AT OPTICAL WAVELENGTHS
Abstract
He-Ne gas lasers at both 1.15 microns and 6328 angstroms have been successfully operated during the past quarter. These lasers are of conventional design and the results have demonstrated the soundness of the apparatus and the fabrication techniques. Detailed calculations indicate that the output power of a two-region He-Ne laser may not be limited by He metastable-metastable ionizing collisions for levels up to about two orders of magnitude higher than are available from conventional gas lasers. The limiting level will be even higher if the cross section is smaller than the pessimistic value assumed in the calculations. The results of further design calculations are also included in this report. Fabrication techniques for a gridded laser tube have been largely developed, and construction is proceeding. Another scheme for achieving higher output powers has been considered, but it poses some practical problems. The two-region laser still seems to offer more promise than any other type of gas laser.
