Some of the most recent developments in primary and secondary solar concentrators were firstly presented. A novel three-dimensional elliptical-shaped Fresnel lens analytical model was put forward to maximize the solar concentration ratio of Fresnel-lens-based solar concentrators. By combining a Fresnel lens with a modified parabolic mirror, significant improvement in solar laser efficiency was numerically calculated. A fixed fiber light guide system using concave outlet concentrators was proposed. The absence of a solar tracking structure highlights this research. By shaping a luminescent solar concentrators in the form of an elliptic array, its emission losses was drastically reduced. Simple conical secondary concentrator was effective for thermal applications. New progresses in solar-pumped lasers by NOVA University of Lisbon were presented. By adopting a rectangular fused silica light guide, 40 W maximum solar laser power was emitted from a single Ce:Nd:YAG rod. An aspheric fused silica secondary concentrator and a small diameter Ce:Nd:YAG rod were essential for attaining 4.5 % record solar-to-laser power conversion efficiency. A novel solar concentrator design for the efficient production of doughnut-shaped and top-hat solar laser beams were also reported. More importantly, a novel solar concentrator approach for the emission of 5 kW-class TEM00 mode solar laser beams from one megawatt solar furnace was put forward at the end of this book, revealing promising future for solar-pumped lasers.Technology: general issuesbicsscHistory of engineering & technologybicsscluminescent solar concentratorsolar spectrum splitterpower generation in spacemicroalgaebeam mergingmultirodNd:YAGsolar furnacesolar flux homogenizersolar laserTEM00-modesolar pumpingtwisted light guidetop hatdoughnut-shapednanofluidconical concentrator systemperformance comparisonthermal efficiencyFresnel lensGaussian sourcegroove numbersolar fluxoptical efficiencyfull width at half maximumconcentratorlight guideoptical fiber solar systemsolar daylightinglaserparabolic mirrorsolar concentratorcollecting efficiencyconical solar concentratorperformance analysissolar energyCe:Nd:YAGaspherical lensside-pumpeduniformitylight-guidehomogenizersolar-pumped laserlaser efficiencyTechnology: general issuesHistory of engineering & technologyLiang Daweiedt1337676Zhao ChangmingedtLiang DaweiothZhao ChangmingothBOOK9910674052203321Challenge and Research Trends of Solar Concentrators3057191UNINA
