Abstract :
/sup 12/CD/sub 3/OH and /sup 13/CD/sub 3/OH have produced hundreds of far-infrared laser lines in the 22 to 3030 /spl mu/m wavelength region when optically pumped by CO/sub 2/ lasers. In this work, we report the discovery and frequency measurement of optically pumped laser emissions from these molecules in the wavelength range from 45.3 to 103.3 /spl mu/m.
