Proceedings of a workshop held January 1991, in Cortina d'Ampezzo, Italy, encompass a wide range of topics from fundamental problems in quantum mechanics to applications in optical technology. A major emphasis is on measurements made possible by recent advances in the generation and detection of lig

The recent generation in the laboratory of phase squeezed and intensity squeezed light beams has brought to fruition the theoretical predictions of such non-classical phenomena which have been made and developed in recent years by a number of workers in the field of quantum optics. A vigorous development is now underway of both theory and experiment and the first measurements have been coi: Jfirmed and extended already in some half dozen laboratories. Although the fields of application of these novellight sources are as yet somewhat hazy in our minds and some inspired thinking is required...
