Quantum cascade laser (QCL)


QCL is a semiconductor laser with emission wavelength in the mid-IR range (4 um to 10 um). Because its emission principle is completely different from normal LDs, the QCL has gained attention as an lnnovative solution for mid-IR applications such as trace gas analysis in environmental monitoring.
