　　The birth of quantum electronics in the middle of the 20th century and the subsequent discovery of the laser led to new trends in physics and a number of photonic technolgies. Advances in Laser Physics is dedicated to Peter Franken, a pioneer of nonlinear optics, and includes papers by the founders of quantum electronics, Aleksandr Prokhorov, Nicolaas Blombergen, and Norman Ramsey. The topics covered range from astronomy to nuclear and semiconductor physics, and from fundamental problems in quantum mechanics to applications in novel laser materials and nanoscience.
