Since the initial laser beam in 1960, use of lasers has mushroomed, opening new frontiers in medicine, manufacturing, communications, defense, and information storage and retrieval. Lasers: Invention to Application brings together a series of chapter

We present the shadow mask MBE regrowth technique, with which we are able to grow 3D structures, size ranging from several to hundreds of μm, that enable vs to directly contact quantum structures as thin as 10 nm and to make interdigitated contacts.

A five-mirror cavity suitable for passively mode-locked dye lasers is analyzed and also modeled on the computer. Simple approaches for constructing a compensated cavity are shown. Experiments are performed confirming the theoretical results.

The thermal self-phase modulation effect, arising when a laser beam passes through absorbing materials, is used to measure the product of absorption coefficient and dn/dT (change of refractive index with temperature). By adding a dye so that absorpti

Cross-phase modulation in a semiconductor laser diode amplifier is reported. A simple expression for the chirp imparted on a weak signal pulse by the action of a strong pump pulse is derived. A novel dispersive technique for characterizing the result

Summary form only given. The many quasi-optical techniques used with microwaves are now well-known, but the development of these provides a number of interesting case histories. In addition to the ties based upon field theory, there were important in

We have constructed two kinds of external cavity semiconductor laser. The first one is a diffraction feedback system consisting of a collimating lens, a diffraction grating and a mirror controlled by a PZT element. The second one is a dispersion feed
