Abstract

Intense superradiant emission has been observed from methyl fluoride excited by 0.6‐MW pulses from a high‐pressure CO2 laser. Pulses of ∼ 1 kW with a duration of ∼ 150 nsec have been obtained from a 5‐m‐long 40‐mm‐diam cell containing 0.7 Torr of methyl fluoride. This output represents an efficiency of converting infrared photons to far‐infrared photons of ∼ 5%. Evidence for partial waveguiding in the cell and for phase‐coherent amplification are presented.
