Abstract

A new, high-resolution, highly efficient, cw, CO/sub 2/ laser oscillating on more than 250 lines including over 40 lines in the new 9 /spl mu/m hot band has been built at NIST, Boulder. The frequencies of the 9 and 10 /spl mu/m hot band lines and high J (to J=66) regular band lines of /sup 12/C/sup 16/O/sub 2/, which now fill the gap between the 9 and 10 /spl mu/m regions, have been locked to saturated fluorescence signals in CO/sub 2/, and measured. New molecular constants and more accurate frequencies of the four common isotopes of CO/sub 2/ have been obtained.<>
