A quantum cascade laser-pumped molecular laser tunable over 1 THz

open access: yesAPL Photonics, 2022
Despite decades of research, no frequency tunable sources span the terahertz gap between 0.3 and 3 THz. By introducing methyl fluoride (CH3F) as a new gain medium for a quantum cascade laser-pumped molecular laser (QPML), we demonstrate continuous-wave ...
