WA1 - Far-infrared molecular lasers
IEEE Journal of Quantum Electronics, 1973A summory is presented of recent accomplishments and the state of the art of far-infrared (far-IR) molecular lasers. Problems of excitation, laser line assignments, relaxation, and absolute frequency measurements are discussed. Predictions of future far-IR developments are made.

Experiments on a Far Infrared CN Laser
Japanese Journal of Applied Physics, 1967The characteristics of a CN laser with an external mirror operated with the pulsed or d.c. discharges are described. The maximum laser output power is obtained with a coupling mirror of suitable dimension. The laser can oscillate when a metal mesh is used as a resonator mirror. Data on the laser output vs.

FAR Infrared Laser Assignments For Methylamine
SPIE Proceedings, 1988High-resolution FTIR spectroscopy of the C-N stretching band of CH3NH2 has permitted location of several coincidences with CO2 laser lines, and identification of FIR laser transitions optically pumped by these lines. With the use of previous FIR spectroscopic results, it has been possible to form closed frequency combination loops to support the ...

Optically Pumped Far Infrared Lasers
1985The 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 ...

Optically pumped far infrared lasers
Infrared Physics, 1989Abstract The far-infrared (FIR) region of the electromagnetic spectrum is commonly thought of as the wavelength region ≈ 30μm-≈2 mm. Thus, the FIR wavelength region is located between the more familiar areas of microwaves and optics. Primarily due to the lack of FIR sources and detectors, the FIR region is difficult to access and therefore relatively

A grazing incidence far-infrared laser
1983 Eighth International Conference on Infrared and Millimeter Waves, 1983The introduction of gratings at grazing incidence in tunable dye lasers improved considerably their performance. In this paper we present the first grazing incidence far-ir gas laser, its characteristics and relations to distributed feedback gas lasers.

Applications of Far Infrared Lasers
1976The earliest useful sources of coherent radiation in the far infrared or submillimeter region were the electron tube devices including harmonic generators and carcino-trons. These have been used for molecular spectroscopy [1] and for resonance studies of solids [2][3].

The divergence study of far infrared laser
International Conference on Millimeter and Submillimeter Waves and Applications 1994, 1994This paper reports the divergence study of optically pumped far infrared laser with wave lengths of 118P m, 447P m and 890P m. A special device of scanning, recording and detecting system is used in order to obtain the laser beam divergence.

Growth of emission in a far infrared laser
IEEE Journal of Quantum Electronics, 1983When the pump power is switched on, the output power of an optically pumped far infrared laser (FIR) grows up with a time delay of the order of 5-50 \mu s and a rise time of 1-10 \mu s in typical operating conditions. The buildup process is aperiodic at low FIR saturation and damped oscillations appear at the onset when the FIR transition is saturated.

Far-infrared laser power measurements
Proceedings of the IEEE, 1967Measurments of the peak and average output power of a 337-micron cyanide laser are reported. The tests served to indicate the usefulness at this high frequency of available oversize waveguide instrumentation-- a room-temperature average-power measurig bolometer, a liquid helium-cooled InSb detector-mixer and a double-prism attenuator.
