A Compact Four-Wavelength Quantum-Cascade Laser Source

A four-wavelength quantum-cascade (QC) laser source that operates using a single current channel is presented. The source includes two different heterogeneous cascade QC lasers, one with emission wavelengths of 7.0 mum and 11.2 mum, and the other with 8.7 mum and 12.0 mum . For 3.0-mm and 3.5-mm cav...
