This volume provides the first comprehensive overview of the modern use of ultraviolet laser radiation in the processing of materials. Lasers operating at ultraviolet wavelengths combine the ability to vaporize the most refractory of materials with the precision to ablate micron-sized holes in polymers and remove thin layers from the cornea for corrective surgery of the human eye. This book explores the use of UV laser radiation for the ablation and deposition of metals, insulating solids, polymers, semiconductors and superconductors. It emphasizes the physical mechanisms accompanying these processes and the conversion of intense UV radiation to photothermal and photochemical energy in irradiated materials. This will be an invaluable sourcebook of current information in the rapidly developing field of laser applications for engineers, scientists, researchers and students in universities, government laboratories and the private sector. A valuable supplementary text for graduate courses in materials science.

This Conference on biomedical applications of. lasers ~Ias organized by the Quantum Electronics Divisional Board of the European Physical Society (E.P.S.) and held at the Villa of Poggio Imperiale in Florence, September 3-6, 1979. As kno~m, laser surgery (especially microsurgery and endoscopic photo coagulation) has recently made important progress, and the field is expand i ng rapidly. Very significant applications of lasers have also been achieved in Bi ology during recent years (cell microsurgery, cell counting and sorting, cytofluorimeter devices, etc.) and the potential of laser techniques in this field is nO~1 sufficiently well establ ished. A new class of applications of laserradiJtion in Medicine has recently been made possible by important results obtained with low intensity (non coagulative) visible lasers, such as photodynamic therapy of tumors. At the same time important branches of Medicine, where light effects are studied and optical techniques are presently used for a certain number of clinical applications, such as dermatology and pediatry, appear to be still in their infancy as far as the proper use of optical radiation and techniques, and the understanding of fundamental photoinduced biological processes are con cerned. Moreover, laser photobiology appears a very promising field for the investigation of fundamental processes at the biomolecular level.

This report summarizes recent efforts towards the development, improvement, and use of tunable laser systems and novel coherent light techniques for high resolution ultraviolet spectroscopy of atoms and molecules. It reports on: (a) studies of atomic hydrogen and deuterium by Doppler-free ultraviolet laser spectroscopy, which have yielded new precision values of the 1S-2S isotope shift and of the 1S ground state Lamb shift; (b) the first demonstration of a novel technique of high resolution laser spectroscopy, using coherent two-photon excitation with multiple light pulses; (c) the status of a search for a hydrogen-laser-pumped tunable ultraviolet laser; and (d) the observation of a quenching of the laser action in xenon fluoride excimer lasers by the vapor of xenon difluoride.
