Design of a stable CW HCN laser for far infrared frequency synthesis
نویسندگان
چکیده
2014 An HCN laser for infrared frequency synthesis has been designed to satisfy both conditions of high frequency stability and ouptut power. The influence of all the descriptive parameters of the laser on its frequency stability and power are analyzed. The optimization of the two above criteria is discussed with emphasis on frequency stability. On the 891 GHz line the laser shows a natural frequency stability (0394f/f) = 5 x 10-9 with an output power of 20 mW-30 mW, and its maximum power is 100 mW.

Spectral analysis of a phase locked laser at 891 GHz, an application of Josephson junctions in the far infrared
2014 We have used a Josephson junction to investigate the spectral purity of an HCN laser which is used in an infrared frequency synthesis chain. To obtain a narrower linewidth from the laser it has been phase locked to a multiplied microwave reference chain. A calculated value for this linewidth was based upon the measured noise spectrum of the microwave source and a theory due to Middleton. O...

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 کاملPressure effects on the frequency of continuous-wave optically pumped far-infrared lasers.
The frequency of the 170.6-microm cw CH(3)OH optically pumped laser emission has been remeasured at different pressures without observing the pressure shift observed by Lawandy and Koepf [Opt. Lett. 5, 383 (1980)]. The far-infrared frequency was synthesized with two stabilized CO(2) lasers. No measurable pressure shift over the operating pressure range of the laser was observed, and the frequen...
متن کاملCharacterization of frequency noise on a broadband infrared frequency comb using optical heterodyne techniques.
We measure the frequency noise across a Cr:forsterite infrared frequency comb through the optical heterodyne beat of different comb teeth against stable continuous wave (CW) lasers. This sensitive measurement shows strong correlations of the frequency noise between spectral components of the comb, relative to a fixed optical frequency near the 1.3 micron carrier of the Cr:forsterite laser. The ...
متن کاملGeneration of tunable far-infrared radiation with a quantum cascade laser.
We demonstrate the generation of cw tunable far-infrared radiation by mixing a quantum cascade laser and a CO>(2) laser in a W-Ni metal-insulator-metal diode. The first known spectroscopic application to the recording of an H(79)Br transition near 4.47 THz is reported.
