We present the frequency measurements of 14 Far-Infrared (FIR) laser lines. We use the heterodyne technique of mixing FIR laser transitions and microwave radiation on a MIM point contact diode to determine the FIR frequencies. The main motivation was to measure the frequency of laser lines of meterological interest, around the 1.6 and 1.2 THz regions. We also present 15 new FIR laser lines we found while performing the frequency measurements, with wavelengths ranging from 90 mum to 819.2 mum. All of them are characterized in wavelength, polarization, intensity, working pressure and absorption offset.

Abstract
We present the frequency measurements of 14 Far-Infrared (FIR) laser lines. We use the heterodyne technique of mixing FIR laser transitions and microwave radiation on a MIM point contact diode to determine the FIR frequencies. The main motivation was to measure the frequency of laser lines of meterological interest, around the 1.6 and 1.2 THz regions. We also present 15 new FIR laser lines we found while performing the frequency measurements, with wavelengths ranging from 90 mum to 819.2 mum. All of them are characterized in wavelength, polarization, intensity, working pressure and absorption offset.File in questo prodotto:
