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-wa

The quantum cascade laser pump molecular laser (QPML) is a tunable source of terahertz frequencies operating at room temperature that can easily scale beyond the milliwatt level. We present here new progress in QPML research.

By introducing methyl fluoride (CH$_3$F) as a new gain medium for a quantum cascade laser-pumped molecular laser (QPML), we demonstrate continuous-wave lasing from more than 120 discrete transitions spanning the frequency range 0.25 to 1.3 THz. The u

Gaseous ammonia has previously been demonstrated as a compelling gain medium for a quantum cascade laser pumped molecular laser (QPML), exhibiting good power efficiency but limited tunability. Here we explore the potential of the ammonia QPML to prod

We demonstrate and characterize a new quantum cascade laser-pumped molec- ular laser using methyl fluoride as its gain medium. We show that a laser using this gain medium can exhibit a low pump threshold while allowing emission over more than 100 lin

We demonstrate a quantum cascade laser-pumped terahertz laser using methyl fluoride gas. The large dipole moment of this molecule allows for a low threshold laser with frequency tunable emission spanning more than one terahertz.

The global defense community requires new approaches for standoff detection of chemical, biological, radiological, nuclear and explosive (CBRNE) threats. Such standoff detection methods must be capable of discriminating the target hazardous materials

The design and assembly of a unique infrared (IR) optical-fiber combined quantum cascade laser (QCL) system is described. This system integrates the output from four individual QCL modules, using infrared optical fibers, into a single output aperture
