Notes: We report the generation of pulsed optically pumped far-infrared (FIR) radiation with a repetition rate of 200 kHz. These pulses were obtained in a straightforward method by pumping a FIR resonator with a high repetition rate, rf-excited, waveguide CO2 laser. Pulses approximately 50 ns wide were generated both at 432.6 μm in HCOOH, and 117.7 μm in CH2F2. The pulse width of the FIR radiation was studied as a function of the CO2 pulse width, and the relative delay between the two was measured. Based on this data we conclude that the FIR radiation was gain switched and of a duration which was a function of either the gain bandwidth of the FIR transition, or more likely the FIR cavity parameters.

Notes: [Auszug] SIR John Maddox (Nature 366, 717; 1993) presents four basic reasons for the success of the Japanese Institute for Space and Astronautical Science (ISAS). I was reminded immediately of a British research institute which up to about 20 years ago fitted his criterion quite closely. It was (1) ...
