Abstract

We show new results in modulating and modifying Quantum Cascade (QC) lasers to make them more suitable for chemical sensing spectroscopy. Spectroscopy results using QC lasers are demonstrated with whispering gallery mode CaF₂ disc/ball, saturated absorption in hollow waveguide and direct chemical analysis in water.
