Abstract

Our collaborative team is developing new experimental set-ups based on heterodyne mixing of synchrotron radiation (extracted by the AILES beamline of SOLEIL) with various Local Oscillators (LOs). In the sub-millimeter and THz regions (defined as 0.1--1 THz), LOs from electronic techniques are easy to implement through the use of multiplication chains. However, it is more challenging to produce fixed LOs in the far-IR domain (1--6 THz). The recent development of a new generation of molecular lasers pumped by 10 $\mathrm{\mu}$m QCLs\footnote{Pagies et al., APL Photonics 1 (2016)} allows us to generate many more far-IR frequencies than the previous approach which used CO$_2$ lasers as a pump source. The difficulty in this technique stems from selecting the proper far-IR transitions that both involve rotational states susceptible to lase and that are accessible with our 10 $\mathrm{\mu}$m QCL source. We will present our program making use of HITRAN, JPL, CDMS, and ExoMol databases to produce lists of far-IR lasing frequencies.
