Abstract :
The CH317OH isotopic form of methanol has been investigated as a far-infrared laser medium for the first time. Using two distinct experimental systems, this investigation has resulted in the discovery of twelve far-infrared laser emissions that range in wavelength from 69.7 to 642.9 μm. Along with the wavelength, each laser emission is reported with its optimal operating pressure and relative intensity. The frequency for the 69.7 μm line was measured to be 4 302 957.7 ± 1.0 MHz and is reported with the CO2 pump laser´s offset frequency relative to its center frequency.
