This book systematically introduces the single frequency semiconductor laser which is widely
used in many vital advanced technologies such as the laser cooling of atoms and atomic clock
high-precision measurements and spectroscopy coherent optical communications and advanced
optical sensors. It presents both the fundamentals and characteristics of semiconductor lasers
including basic F-P structure and monolithic integrated structures interprets laser noises and
their measurements and explains mechanisms and technologies relating to the main aspects of
single frequency lasers including external cavity lasers frequency stabilization technologies
frequency sweeping optical phase locked loops and so on. It paints a clear physical picture
of related technologies and reviews new developments in the field as well. It will be a useful
reference to graduate students researchers and engineers in the field.
