Paper Abstract

In order to produce ultrashort FIR laser pulses we have investigated the superradiance and Raman emission of various molecular transitions optically pumped with the pulses of 10 micrometers hybrid or high-pressure single-mode carbon dioxide lasers truncated with 10 ps. furthermore we have truncated directly the FIR laser pulses with the first FIR plasma shutter developed in our laboratory. In our experiments we have observed new phenomena which include, for example, new interrelations between superradiance, swept-gain superradiance and Raman emission, anticorrelated fluctuations of pump radiation versus FIR emissions, first OFID of 10-micrometers carbon dioxide laser pulses with FIR emitting molecular gases.
