Abstract
High-power mid-IR coherent light sources operating either at ambient or thermoelectric cooler temperatures are required for numerous applications such as IR countermeasures and communications, remote chemical sensing for pollution and drug monitoring, chemical process control, laser surgery etc. In this paper, we report the development of two novel mid-IR sources: an intersubband based second-harmonic generator with voltage-controlled phase-matching and an interband cascade laser (ICL).
