To obtain laser oscillations from easily dissociative molecules on discharge excitation, a transverse-flow FIR laser tube was designed and constructed. A flowing gas region of about 35cm long is located inside a 50cm F-P resonator in this tube. Infrared-active formaldehyde as a sample gas, laser oscillation was observed at the wavelength of 122.8±0.2 μm under the conditions of the flow speed from 0.2 to 1.0 m/sec and the pressure from 0.4 to 2.8 Torr. Peak voltage from 1.8 to 5.9 kV was applied with the etition of 8.5 Hz.

FIR Laser Oscillation from H₂CO in a Longitudinal-Flow Tube

Previously, we could observe stimulated emission only for several pulses just after the initiation of discharge in a longitudinal-flow H₂CO laser. Following a success in a transverse-flow tube, lasting laser oscillation was obtained from H₂CO in a 3-m longitudinal-flow tube by improving a speed and a pulse repetition. Ten FIR lasing lines have been observed and six of them are new lines. We also observed some cascade/competitive relations among some of these lines.
