Because of very strong molecular absorption between 2 mm to 1000 mm, compact semiconductor lasers in this spectral range are ideal components for a wide variety of applications ranging from ultra–sensitive detection of molecules, to the study of fine structures of molecules, to studies of the origin of the universe. However, because of the very rapid progress made in these long–wavelength semiconductor lasers in recent years, no comprehensive information covering the entire field has been available up to this point.
Long–Wavelength Infrared Semiconductor Lasers fills the need for a reference that covers the vast scope of coherent semiconductor sources that emit in this important spectral region. Written by today’s foremost experts in the field, the book covers the latest knowledge in the areas of:
- Quantum cascade lasers
- Interband mid–infrared lasers fabricated from InGaAs,antimonides, and lead–salt materials
- Hot–hole lasers
Researchers, application engineers, graduate students, and others who develop mid– to far–infrared emitters and use them for spectroscopy, astrophysics, environmental monitoring, and process control will find Long–Wavelength Infrared Semiconductor Lasers a necessary resource.
