Abstract :
We report the observation and characterization of seven new far-infrared (FIR) laser lines from H12COOH and H13COOH in the range 232.2 to 746.6 μm optically pumped by a wide-tunability waveguide CO2 laser. Their absorption frequency is outside of the tuning range of a conventional CO2 pump laser
