Abstract:Molecular lasers pumped by quantum cascade laser (QCL) open new possibilities for THz generation and its numerous applications, in particular, for high resolution molecular spectroscopy. In this article, a THz water laser pumped by a mid-infrared QCL was demonstrated using the broad tunability of the pump laser. Twenty D2O laser lines were measured under a continuous wave pumping regime, in a spectral range expending from 63 to 177 cm−1 (1.9–5.3 THz), and with an output power ranging from tens to hundreds of μ… Show more
