    The development of short-wavelength lasers is reviewed. Three pumping mechanisms have been demonstrated which produce lasing at wavelengths from 3 to 100 nm. These mechanisms include electron-collisional excitation, electron-ion recombination, and photo-excitation. Examples of X-ray lasers and future directions of the field are discussed View full abstract»

    Recent developments in β-barium borate (BBO), lithium triborate (LBO), and potassium titanyl phosphate (KTP) optical parametric oscillators are reviewed. It is noted that, with suitable nonlinear optical crystals and pump sources, virtually any wavelength ranging from the UV to the mid IR can now be reached with optical parametric oscillators. The technology is better developed at the present... View full abstract»

    Recent progress in the development of the concept and technology of semiconductor quantum wire (QWR) lasers is reviewed. In these quasi-one-dimensional structures, optical gain is provided by charge carriers that are quantum mechanically confined in two dimensions within wire-like active regions. These devices are expected to exhibit improved laser performance, including extremely low threshold cu... View full abstract»

    Several methods have been proposed for the generation of photon-number-squeezed (sub-Poisson) light by imparting to the photon stream and anticorrelation that regularizes the times of arrival of the photons. This is accomplished by means of control of the excitation or emission process or by feedback, using a copy of the photon point processes when the emissions occur in parts. Possible advantages...
