Optically Pumped Far Infrared Lasers
Abstract
The search for efficient and powerful sources of coherent radiation spanning the widest possible spectral range is a major task in the fields of Quantum electronics and Laser spectroscopy. Until the discovery in 1970 1 of the optically pumped Far Infrared (FIR) lasers, the submillimeter range of the spectrum had been almost barren due to the lack of radiation sources. Before 1970, the FIR portion of the electromagnetic spectrum was only very sparsely covered by molecular glow discharge lasers (HCN, DCN, H2O) and the list of available laser lines was rather poor2 Since 1970 more than two thousand optically pumped FIR laser lines throughout the 0.03 to 2 mm region were discovered, some providing hundreds of Kilowatts of milliwatts of continous power.
