Frequencies of Optically Pumped Sub-Doppler Far-Infrared Laser Lines of Methanol.
Sub-Doppler signals from the gain curves of four lines of a transversely pumped far-infrared methanol laser were used to stabilize the frequencies of the laser. The frequencies of four of the strongest FIR laser lines (70, 119, 123, and 570 µm) were measured. Lasers locked to these lines have a frequency reproducibility of a few parts in 10(8) and an uncertainty of less than 30 kHz. Copyright 1...
متن کاملCharacterizing Far-infrared Laser Emissions and the Measurement of Their Frequencies.
The generation and subsequent measurement of far-infrared radiation has found numerous applications in high-resolution spectroscopy, radio astronomy, and Terahertz imaging. For about 45 years, the generation of coherent, far-infrared radiation has been accomplished using the optically pumped molecular laser. Once far-infrared laser radiation is detected, the frequencies of these laser emissions...
متن کاملNew FIR laser lines from hydrazine and assignments
Our new waveguide pulsed CO2 laser, with peak powers above 1 kW, has allowed us to observe 24 new farinfrared laser lines emitted by hydrazine. Each of them is characterized in wavelength, relative polarization, intensity, optimum operating pressure and pump offset from the center of the exciting CO2 line. These new laser emissions either form pairs sharing the same pump line, or complete such ...
متن کاملShort-wavelength far-infrared laser cavity yielding new lines in methanol.
We report 16 new laser lines generated in a short-wavelength far-infrared Fabry-Perot laser cavity. The CO(2) pump laser is coupled into the far-infrared laser outside the far-infrared laser mode, and the cavity uses a 45 degrees adjustable output coupling mirror; this combination results in a low-loss Fabry-Perot cavity for wavelengths below 150 microm. The new lines are of medium and strong i...
متن کاملFar-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.' ...
