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. 606 $aTechnology: general issues$2bicssc 606 $aHistory of engineering & technology$2bicssc 610 $aluminescent solar concentrator 610 $asolar spectrum splitter 610 $apower generation in space 610 $amicroalgae 610 $abeam merging 610 $amultirod 610 $aNd:YAG 610 $asolar furnace 610 $asolar flux homogenizer 610 $asolar laser 610 $aTEM00-mode 610 $asolar pumping 610 $atwisted light guide 610 $atop hat 610 $adoughnut-shaped 610 $ananofluid 610 $aconical concentrator system 610 $aperformance comparison 610 $athermal efficiency 610 $aFresnel lens 610 $aGaussian source 610 $agroove number 610 $asolar flux 610 $aoptical efficiency 610 $afull width at half maximum 610 $aconcentrator 610 $alight guide 610 $aoptical fiber solar system 610 $asolar daylighting 610 $alaser 610 $aparabolic mirror 610 $asolar concentrator 610 $acollecting efficiency 610 $aconical solar concentrator 610 $aperformance analysis 610 $asolar energy 610 $aCe:Nd:YAG 610 $aaspherical lens 610 $aside-pumped 610 $auniformity 610 $alight-guide 610 $ahomogenizer 610 $asolar-pumped laser 610 $alaser efficiency 615 7$aTechnology: general issues 615 7$aHistory of engineering & technology 700 $aLiang$b Dawei$4edt$01337676 702 $aZhao$b Changming$4edt 702 $aLiang$b Dawei$4oth 702 $aZhao$b Changming$4oth 906 $aBOOK 912 $a9910674052203321 996 $aChallenge and Research Trends of Solar Concentrators$93057191 997 $aUNINA
