Laser oscillations at submillimetre wavelengths from pulsed gas discharges in compounds of hydrogen, carbon and nitrogen

Stimulated emission at ten new wavelengths between 126 and 373¿m was obtained with dimethylamine. The stronger lines were also obtained with seven related compounds and with several mixtures, notably methane and ammonia. A new spectrum (four lines between 181 and 205¿m) was obtained with a mixture of deuterium and bromine cyanide. The radiation is tentatively attributed to HnCN with n >1.
