Frequency measurements of optically pumped far-infrared laser lines
- Univ. Estadual de Campinas (Brazil). Inst. de Fisica
In this work, the authors report the frequency measurements of optically pumped Far-Infrared (FIR) laser lines. They use the heterodyne technique of mixing FIR laser radiation and microwave radiation on a Metal-Insulator-Metal (MIM) point contact tunnel diode, to determine the FIR laser frequencies. The two FIR laser systems, consisting of CO{sub 2} waveguide pump lasers and Fabry-Perot FIR laser cavities, and MIM diode were developed by the authors. To check the system, they have measured some FIR laser line frequencies previously reported in the literature. An average fractional frequency reproducibility of {+-}7 {times} 10{sup {minus}7}, between their measurements and the previous ones, permit them to use their system to measure five new FIR laser frequencies.
