Abstract

Broad tunability in the mid-IR (~3-12 μm) is desirable for a number of applications. We have built a number of External Cavity quantum cascade Lasers (ECqcL^TM) that maximize tuning range from the quantum cascade chip. As much as 525 cm^-1 of pulsed and 121 cm^-1 of cw, mode hop-free tuning has been obtained. Various mechanisms for the broadening of the gain of the QC chip are considered.
