Far-infrared CH3F Stark laser.
This Letter reports oscillation of a far-infrared (FIR) waveguide laser on individual Stark components of the 496-,Am transition in CH3 F by the application of an electric field across the laser medium. Stark shifting of vibrational-rotational absorption lines into coincidence with C02-laser pump lines giving rise to FIR oscillation in the rotational transitions was first observed in ammonia.' ...
متن کاملFar Infrared Laser Magnetic Resonance
Within the last few years, laser magnetic resonance (LMR) has emerged as a powerful technique for the detection of transient species in the gas phase and the study of their rotational spectra. The sensitivity of this method is con siderably higher than those of most competing techniques, such as conventional optical and microwave spectroscopy and gas-phase EPR, while the resolution attainable ...
متن کاملTunable Far Infrared Laser Spectroscopy
using C02 laser difference generation in metal-insulator-metal diodes either from the difference between a fixed frequency C02 laser and a tunable waveguide laser, or from the difference between two fixed frequency C02 lasers plus microwave sidebands. is being used to make highly accurate FIR frequency measurements of stable species to serve as frequency and wavelength calibration standards; to...
متن کاملProtoplanetary Gas Disks in the Far Infrared
The physical and chemical conditions in young protoplanetary disks set the boundary conditions for planet formation. Although the dust in disks is relatively easily detected as a far-IR photometric “excess” over the expected photospheric emission, much less is known about the gas phase. It seems clear that an abrupt transition from massive optically thick disks (gas–rich structures where only ∼...
متن کاملThe Berkeley tunable far infrared laser spectrometers
A detailed description is presented for a tunable far infrared laser spectrometer based on frequency mixing of an optically pumped molecular gas laser with tunable microwave radiation in a Schottky point contact diode. The system has been operated on over 30 laser lines in the range 10-100 cmi and exhibits a maximum absorption sensitivity near one part in 106. Each laser line can be tuned by f ...
