摘要： A compact, light weight laser beam combiner includes a pair of concentric annular shells defining an annular cavity of an annular ring resonator having an annular solid laser gain medium disposed therein. The output ends of a plurality of low power and brightness fiber lasers are coupled into the cavity of the resonator such that fiber laser beams cause the gain medium in the resonator cavity to lase and produce an annular beam of laser light. Optical elements of the resonator are operable to feed a first portion of the laser light back through the resonator cavity to support regenerative lasing of the laser medium and to couple off a second portion of the laser light in the form of a circular beam of high power and high brightness laser light. A fluid may be circulated through the resonator cavity to cool the laser medium.

摘要： A spin-coated polymer microcavity for light emitters and lasers producing enhancement of spontaneous emission rate from colloidal CdSe/ZnS core/shell quantum dots embedded in a one dimensional polymer microcavity structure at room temperature. The polymer microcavity structures are fabricated using spin coating. Alternating layers of polymers of two different refractive indices were stacked to form the Distributed Bragg reflectors (DBRs). To achieve high reflectivity, the polymers for the DBR structures were chosen so that they have a relatively high refractive index ratio. The high and low refractive index polymers chosen were poly-N(vinylcarbazole) (PVK) and poly acrylic acid (PAA), with refractive indices of 1.683 and 1.420 at 600 nm, respectively. Thin films of quarter wavelength thickness of the two polymers are alternately spin coated on a glass substrate to make the DBR structures. Greater than 90% reflectivity is obtained using ten periods of the structure. A PVK cavity layer of λ thickness embedded with CdSe/ZnS core/shell quantum dots is sandwiched between two of these DBRs to form the entire microcavity structure. The bottom and top DBRs comprise ten and five periods, respectively.

摘要： The systems and methods herein provide for tuning an optical characteristic of a gain medium for a laser system. For example, a system may include a thermal tuner that dynamically controls the temperature of the gain medium to compensate for thermal mechanical distortions of the gain medium caused by laser energy in the gain medium. In doing so, the tuner may dynamically adjust a coolant temperature and/or a coolant flow rate proximate to the gain medium. Accordingly, heat is dynamically removed from the gain medium so as to adjust for optical distortions in the gain medium. Such a dynamic heat removal may provide a laser system designer with the ability to generate laser energy with controllable predetermined optical wavefronts (e.g., a flat optical wavefront).

摘要： The present invention includes a laser amplifier and a method of making the same. The laser amplifier of the present invention includes a gain medium layer having a first index of refraction, and a coupling layer optically coupled to the gain medium. In the various embodiments described herein, the coupling layer can have a second index of refraction less than the first index of refraction. The laser amplifier described herein can also include an evanescent layer disposed between the gain medium and the coupling layer. The evanescent layer can have a third index of refraction less than the second index of refraction. The laser amplifier provides high power, efficient laser resonance through frustrated total internal reflection and total internal reflection while simultaneously providing for the minimization of waste heat in the gain medium layer.
