CW and pulsed FIR-CO2 hybrid laser with improved efficiency and amplitude stability at short FIR wavelengths
Abstract
For the first time stable CW output of a FIR-CO2 hybrid laser has been achieved at wavelengths shorter than 300 microns. Due to the saturable absorber characteristic of the FIR laser gas, CW or pulsed emission is observed on both, the CO2 and the FIR laser output, depending on the operating conditions. Results are reported on different resonant lines in CH3OH and the 67-micron Raman line in NH3. The good efficiency of this laser is also demonstrated by the excitation of two new emission lines in CH3OH, namely 49 and 56 microns, pumped by 9R(22) and 9R(24), respectively.
