摘要： The laser material of the invention comprises an alkali-halide crystal, with a rocksalt crystallographic structure, containing point defects selected from the group consisting of F.sub.3 or R, F.sub.4 and N.sub.2 color centers. The preferred laser material is based on the neutral "N.sub.2 " color center defect. The alkali halide can be any alkali halide, for example, lithium, sodium, potassium and rubidium chloride, bromide and fluoride. The preferred alkali halide is potassium chloride. The lasers of the invention comprise a stable near-infrared laser which can be tuned in the case of KCl for example from 1.23 to 1.35 .mu.m, and can be optically pumped at 1.06 .mu.m, for example from a Q-switched Nd:YAG laser. The laser of the invention represent the first reported laser based on N.sub.2 -center transitions, and appear to be the first stable laser using a charge-neutral color center in pure alkali halide hosts.

摘要： A portion of the pulsed output of a 3-mirror, folded, astigmatically compensated cavity of a c.w., mode-locked, color center laser is coupled into a single-mode, polarization-preserving optical fiber. Following compression of the pulses by their propagation through the fiber, the shortened pulses, which take the form of essentially solitons, are fed back into the laser cavity so as to coincide and be in phase with the pulses in the laser cavity. Through the process of stimulated emission in the color center crystal, the injected pulses force the laser itself to produce shorter pulses of essentially the same shape as the solitons. Also described are embodiments employing a mode-locked semiconductor, fiber-Raman laser, and unidirectional pulse propagation in the fiber. Two of the fiber-Raman laser embodiments have separate gain and pulse shaping sections of optical fiber joined by an optical fiber directional coupler.

摘要： A method of fabricating a color laser, comprising growing a first thin layer of ionic crystal on a substrate. The crystal can comprise many types of ionic crystals, such as sodium chloride or potassium chloride. A second thin layer of a different type of ionic crystal can be deposited above the first ionic crystal layer, such as lithium fluoride or sodium fluoride. An inert metal layer can be deposited between the first and second layers of ionic crystal and above the second layer of ionic crystal. When the first and second ionic crystal layers are radiated with gamma rays, they form color centers at the spots radiated. Because of the difference in crystalline properties of the two different ionic crystal centers, their color centers have different wavelengths. Each of the ionic crystal layers emit light at different characteristic wavelengths when illuminated at their unique absorption frequencies, and can be made to lase separately.

摘要： A thin layer of ionic crystal is grown on a substrate. The crystal could be any type of ionic crystal, such as sodium chloride or potassium chloride. The crystal is a pure form of the chosen compound and may contain contaminants which would shift the wavelength of created color centers. On top of the first crystal layer, a second thin layer of a different type of crystal is deposited, such as lithium fluoride or sodium fluoride. When these two layers are radiated with gamma rays, they will each form color centers at the spots radiated. Because of the difference in crystalline properties of the two different ionic crystal centers, their color centers would be at different wavelengths. Each of the two separate ionic crystals will emit light at different characteristic wavelengths when illuminated at their unique absorption frequencies. Each layer can be made to lase separately. The top layer has an absorption energy greater than that of the bottom layer, so that the layer energy of the bottom layer absorption peak will pass through the top layer and be absorbed only by the bottom layer. There are many ways of forming F-centers in the two superimposed layers, such as by the use of selective gamma radiation by heating of an anion layer of the particular compound and then depositing the second ionic crystal on the first ionic crystal and then depositing an anion layer on the second crystal and then heating to produce a structure which will lase it to the different frequencies.

摘要： The present invention is directed to a tunable, solid state laser utilizing room temperature, stable, color centers of LiF:F.sub.2.sup.+ ** material. Also disclosed is a method of lasing. An object of the present invention is to develop and optimize LiF:F.sub.2.sup.+ ** thermostabilized active media, to propose a method of pumping, and to realize a room temperature, stable and efficient operation of the color center laser. These and other objects are achieved by introducing special dopants in the crystal at the stage of crystal growing; applying special regimes of ionizing treatment of the crystal, resulting in thermostabilization of the F.sub.2.sup.+ centers in LiF crystals; and utilizing alexandrite laser radiation for color center crystal pumping with a pump radiation frequency which is appropriate for the selective excitation of the F.sub.2.sup.+ color centers. The invention can be used in cases when monochromatic laser emission tunable in the visible-infrared spectral region is required for solving problems in various fields of science and technology such as laser spectroscopy, photochemistry, photobiology, medicine, and the like.

摘要： Optical fibres comprised of a halide glass incorporating color centers, for example fluoride fibres, can behave as a laser or an amplifier when maintained at a low temperature, typically 77.degree. K., and optically pumped. A laser may be comprised by a length of such a fibre (1) wound on a spool (2) and disposed in liquid nitrogen (4), the ends of the fibre are outside of the coolant and associated with input and output mirrors (5,6) which define the extremities of a lasing cavity. An optical pumping signal (7) is provided by a laser (8), for example a Krypton ion laser operating in the visible range. The output of the fibre laser is in the infra-red. Higher gain than with conventional color center lasers is achieved due to the longer interaction length and cooling problems are overcome.
