Short-Wavelength Quantum-Cascade Lasers

Facebook X LinkedIn Email
Recent progress with quantum-cascade lasers makes them attractive sources in the important 3- to 5-μm spectral range.

There exists a gap in the performance of semiconductor lasers in the 3- to 5-μm-wavelength range, a spectral range of particular interest for molecular spectroscopy as well as for applications such as directed infrared countermeasures. The 3- to 5-μm range is important not only because the characteristic absorption bands of, e.g., CO, N2O, HCl and CH2O, lie within this range, but also because there is an atmospheric transparent window in this range. Because semiconductor lasers are compact and robust compared with other lasers, they are a favored candidate to address the 3- to...Read full article
