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 the highest published CW and 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 by defense systems employing directed IR countermeasures as well as other applications such as target designation.

 

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 founded in 2007 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 the Reed Center for Photonics at UW-Madison. The founding team includes Professor Dan Botez, Professor Luke Mawst, Tom Earles, who heads product development, and Rob Marsland who serves as President.
