Opis

Long-wavelength Infrared Semiconductor Lasers provides a comprehensive review of the current status of semiconductor coherent sources emitting in the mid-to far-infrared spectrum and their applications. It includes three topics not covered in any previous book: far-infrared emission from photo-mixers as well as from hot-hole lasers, and InP-based lasers emitting beyond two micrometers. Semiconductor lasers emitting at more than two micrometers have many applications such as in trace gas analysis, environmental monitoring, and industrial process control. Because of very rapid progress in recent years, until this book no comprehensive information beyond scattered journal articles is available at present.

Recenzje

"This book provides an effective means for getting up to speed on practical long–wavelength lasers." ( Optical & Phontonics News, October 2005)

" pulls together a lot of information previously found in an eclectic assortment of journal articles and books. Highly recommended." (E–STREAMS, August 2005)

Blurb

The first comprehensive treatment of long–wavelength laser technology

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
• Photomixers

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.
