摘要： A system and method for generating electrical power from a heat source utilizing both photonic and thermal conversion are disclosed. Specifically, power is generated by coupling photon converters to thermoelectric pairs in a way such that the thermoelectric pairs gain not only the charge carriers (holes and electrons) generated by the photons absorbed by the photon converters, but also the charge carriers generated by excess heat in the photon converters and an added thermal gradient generated by excess energy in the absorbed photons. Heat exchanger variations for such a system are also disclosed. Specifically, heat exchangers with and without photon emitters are disclosed and variants of refractive indices for heat exchanger systems are disclosed.

摘要： A laser medium comprises a solid-state host material and dopant species provided within the solid-state host material. A first portion of the dopant species has a first valence state, and a second portion of the dopant species has a second valence state. In an embodiment, a concentration of the first portion of the dopant species decreases radially with increasing distance from a center of the medium, and a concentration of the second portion of the dopant species increases radially with increasing distance from the center of the medium. The laser medium further comprises impurities within the solid-state host material, the impurities converting the first portion of the dopant species having the first valence state into the second portion of dopant species having the second valence state.

摘要： A laser system includes a laser resonator cavity having a resonant path and an Er,Yb:glass lasing element with an output of from about 1.5 to about 1.6 micrometers within the laser resonator cavity. A diode array optically pumps the lasing element to emit light. A Q-switch lies along the resonant path within the laser resonator cavity. The Q-switch is formed of a host material having a concentration of uranium ions therein, so as to be a saturable absorber of the light emitted by the lasing element. The Q-switch is preferably a uranium-doped fluoride such as U:CaF.sub.2, U:SrF.sub.2, or U:BaF.sub.2.

摘要： A solid state pump cavity comprising a laser rod encased by diffusion bonding inside an outer cladding. The outer cladding provides the ability to efficiently conduct heat away from the laser rod. The outer cladding is also configured to absorb spontaneous laser radiation that would otherwise be re-amplified by the laser rod. Diffusion bonding of the outer cladding to the laser rod forms a seamless optical boundary between the outer cladding and the laser rod. An alternative embodiment of the pump cavity comprises multiple segments of laser rod and outer cladding assemblies coupled together with undoped sections that are diffusion bonded to the ends of the laser rod and outer cladding assemblies.

摘要： A high-Q pump cavity is formed from undoped crystal pieces that are diffusion bonded to a doped core of the same crystal host material. The resulting monolithic pump cavity has 2 opposing convex-curved sides which have a highly-reflective coating on their outer surfaces, except in narrow slit-shaped areas on each curved side through which laser-diode-supplied pump light enters the cavity. The curvature of the two curved sides is such that nearly all the pump light rays that pass through the slit-shaped areas are focussed by the curvature onto the doped core, and rays that enter the cavity are redirected through the doped core many times, resulting in efficient, uniform absorption. The cavity has two opposing flat sides that interface with metal heat sink blocks to facilitate the removal of internally-generated heat. Thermally induced astigmatic lensing caused by this heat is countered by cavity design in which the core shape and the dimensions of the cavity minimize this astigmatism. Embedding a doped crystal core within a crystal of the same material allows the lasing mode size to be larger than the core, allowing the entire doped core to be accessible for efficient extraction, helps reduce parasitic oscillation, and provides highly effective cooling. Furthermore, laser diode light couples directly into the doped core, with close to 100% transport efficiency.
摘要翻译：高Q泵浦腔由扩散接合到相同晶体主体材料的掺杂核心的未掺杂晶体片形成。所得到的整体泵腔具有两个相对的凸曲面，在其外表面上具有高反射涂层，除了在激光二极管供应的泵浦光进入空腔的每个弯曲侧上的狭窄狭缝形区域之外。两个弯曲面的曲率使得通过狭缝状区域的几乎所有的泵浦光线被曲率聚焦到掺杂的芯上，并且进入空腔的射线被重新导向通过掺杂核心多次，导致在高效，均匀的吸收。空腔具有与金属散热块相接合的两个相对的平坦侧面，以便于去除内部产生的热量。由这种热导致的热诱导的散光透镜由空腔设计抵消，其中芯的形状和腔的尺寸使得这种散光最小化。将掺杂的晶体核嵌入相同材料的晶体内可以使激光模式尺寸大于芯，使整个掺杂芯可以方便地进行高效提取，有助于减少寄生振荡，并提供高效冷却。此外，激光二极管灯直接耦合到掺杂的芯中，具有接近100％的传输效率。
