Abstract

We report operation of a passively mode-locked tunable high-pressure CO₂ laser and its use for generation of far-infrared laser pulses. Mode-locking of the CO₂ laser was performed with p-doped Germanium as saturable absorber. We obtained tunable radiation consisting of trains of short pulses of about 1 ns duration. By optical pumping of CH₃F gas superradiant emission resulted in generation of subnanosecond far-infrared laser pulses at a frequency of about 35 cm^-1.
