Lasing Without Inversion

The purpose of the book 'Lasing Without Inversion' is to investigate a few aspects of a novel laser known as lasing without inversion, carried out by the author during recent years, which aims to obtain an insight into the subject and these are discussed in detail. The interest in lasing without inversion (LWI) derives from the potential for low wavelength lasing and the interesting interplay between atoms and light coherence.
