摘要：

The operation of optically pumped FIR molecular lasers in the presence of a static electric field up to 6.5 kV/cm is reported. Wide frequency tuning ranges are demonstrated for the strong CH3F 496 μm, CH3I 508 μm, CH3OH 70.5, 96.5 and 119 μm lines. New Stark tuned lines at about 204 μm are also reported from CH3OH. A Stark frequency tuning range 75 times larger than the Doppler linewidth is measured. The limitations due to the electrical breakdown in the gas and to the Stark detuning of the pump transitions are investigated. The Paschen curves of CH3OH, CH3I, CH3F and CH3CN are measured and design parameters for high efficiency Stark tuned FIR molecular lasers are given. © 1979.
