High Performance Quantum-Cascade Laser

14.11.2012
<strong>Background</strong><br>

The presence and concentration of a number of gases can be detected by measuring the absorption of mid-infrared light with wavelengths near 4 µm. We have developed intense and inexpensive light sources based on quantum cascade lasers (QCLs).<br><br> <strong>Technology</strong><br> The QCL is a new type of semiconductor quantum-well inter-subband device, with a unique material combination and sequence with very large energetic separation of subbands. The QCL-structures have wavelengths between 3-5 µm, emitting within the first atmospheric window. Besides the sensing of organic gases, laser emission in the first atmospheric window has application in free space communication, collision-avoidance radars, cruise-controllers, targeting and “blinding” infrared detectors and cameras. <br><br>

<b>Benefits: </b><br> <ul> <li>First QCL operating in the 3,5-4,5 µm range at room temperature.</li> <li>240 mW output power; a cryogenic operation 6W output peak power (world record).</li> <li>Tunable.</li> <li>Need no cryogenic cooling (lead-salt lasers) or complex optics (“class-B lasers”)</li> </ul> <p><strong>IP Rights</strong><br> DE Patent DE 10 2004 009 531 B4<br> US Patent US 7,848,376 B2 <br> <br> <strong>Origin</strong><br> Humboldt-Universität zu Berlin</p>
