Capacitive-mesh output couplers for optically pumped far-infrared lasers.
The use of capacitive-mesh output couplers for optically pumped far-infrared molecular lasers has been extended throughout the far-infrared spectrum, between 42 microm and 1.2 mm, and the optimum grid constants have been found for several lines. At shorter wavelengths, performance has been improved by the use of a novel hybrid capacitive-mesh hole output coupler.
متن کاملFrequencies 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 کاملOn the Assignment of Optically Pumped Far-Infrared Laser Emission from CH(3)OH.
Progress in the analysis of the infrared spectrum of CH(3)OH in the 930-1450 cm(-1) region has led to assignments, confirmations, or new insights for a number of far-infrared laser (FIRL) transition systems optically pumped by CO(2) lasers. Many of the systems involve FIRL transitions among the CO-stretching, CH(3)-rocking, OH-bending, and CH(3)-deformation vibrational modes, giving useful info...
متن کاملFrequency stabilization of an optically pumped far-infrared laser to the harmonic of a microwave synthesizer.
Measurements of the frequency stability of a far-infrared molecular laser have been made by mixing the harmonic of an ultrastable microwave source with a portion of the laser output signal in a terahertz (THz) Schottky diode balanced mixer. A 3 GHz difference-frequency signal was used in a frequency discriminator circuit to lock the laser to the microwave source. Comparisons of the short- and l...
متن کاملOptically pumped tunable HBr laser in the mid-infrared region.
An optically pumped tunable HBr laser has been demonstrated for the first time. The pump source was a single-frequency Ho:YLF laser and amplifier system, which was locked to the 2064 nm absorption line of HBr. Laser oscillation was demonstrated on 19 molecular transition lines, which included both the R-branch (3870-4015 nm) and the P-branch (4070-4453 nm), by the use of an intra-cavity diffrac...
