Intraband’s QCL Technologies
Working together with the University of Wisconsin-Madison, Intraband has developed new Quantum Cascade Laser (QCL) technologies that enable high-power, high-efficiency, reliable QCL operation with excellent beam quality.
These technologies include QCL-design approaches we have used to achieve 2.6-W CW and 8-W peak-pulsed powers from MOCVD-grown QCL single edge emitters. The company also has technologies for surface emitting and coherent arrayed QCLs.
Intraband develops QCL technologies for a variety of applications including: defense systems, lasers for research & development, industrial lasers, sensor systems, and medical applications.
Technology Applications
Defense Systems
High-power midwave-infrared (MWIR) lasers are used in defense systems employing directed IR countermeasures as well as other applications such as covert communications.
Lasers for R&D
Intraband’s patented high-power QCL technology can be adapted to your specific application. Contact us to explore how our custom high-power, CW or quasi-CW QCLs can meet your needs.
Industrial Lasers
Efficiency, power, and beam quality are critical in applications requiring precise energy deposition for marking or cutting. QCLs can be advantageous when marking or cutting materials that absorb strongly in the 4 to 10 μm wavelength region.
Sensor Systems & Medical Applications
QCL wavelengths match up well with the “fingerprint” regions of the infrared where most molecules have unique, fundamental absorption features. High power and efficiency are needed to sense chemicals, explosives, and biological substances from a distance.
About Intraband
Intraband, LLC was established to develop QCL products exploiting the bandgap engineering capability and product reliability provided by MOCVD growth. Over the past ten years, working together with the University of Wisconsin-Madison, the company has developed new QCL technologies that enable high-power, high-efficiency, reliable QCL operation with excellent beam quality.
Intraband is based at the University Research Park in Madison, WI, with research operations carried out at there and at the Reed Center for Photonics at UW-Madison. The management team includes Professor Dan Botez, Professor Luke Mawst, and Rob Marsland who serves as President.
