Highly Efficient QCL Could Provide Compact and Portable Source of Mid-Infrared Radiation

A highly efficient quantum cascade laser (QCL) that operates continuous wave (CW) at room temperature could provide a compact, portable and cost-efficient source of mid-infrared radiation, say researchers in the US. Their QCL emits at 4.5 microns, has a wall plug efficiency of over 9.3% and a CW output power of 675mW. Wall plug efficiencies greater than 18% are also reported for devices at a temperature of 150K, with CW output powers of more than 1W.
