When analyses need rapid measurements, cost effective monitoring and miniaturization, tunable semiconductor lasers
can be very good sources. Indeed, applications like on-field environmental gas analysis or in-line industrial process
control are becoming available thanks to the advantage of tunable semiconductor lasers.
Advances in cascade lasers (CL) are revolutionizing Mid-IR spectroscopy with two alternatives: interband cascade lasers
(ICL) in the 3-6μm spectrum and quantum cascade lasers (QCL), with more power from 3 to 300μm. The market is
getting mature with strong players for driving applications like industry, environment, life science or transports.
CL are not the only Mid-IR laser source. In fact, a strong competition is now taking place with other technologies like:
OPO, VCSEL, Solid State lasers, Gas, SC Infrared or fiber lasers. In other words, CL have to conquer a share of the
Mid-IR application market.
Our study is a market analysis of CL technologies and their applications. It shows that improvements of components
performance, along with the progress of infrared laser spectroscopy will drive the CL market growth. We compare CL
technologies with other Mid-IR sources and estimate their share in each application market.
