| Laser Sets Records in Power and Energy Efficiency
Northwestern University (Press Release) - July 18, 2007
The Center for Quantum Devices, has recently made great strides in laser design, material growth and laser fabrication that have greatly increased the output power and wall-plug efficiency of Quantum Cascade Lasers. The CQD has demonstrated lasers emitting at wavelengths of 4.5 microns, capable of producing over 700 milli-Watts of continuous output power at room temperature and more than one Watt of output power at lower temperatures. These lasers have a 10 percent wall-plug efficiency at room temperature and more than 18 percent wall-plug efficiency at lower temperatures, which is far superior to any competing laser technology at this wavelength. ...
