非成像光学技术允许使用蓝宝石聚光器产生世界纪录的太阳光强度，72 W/mm（2）。这样的强度超过太阳表面本身的光强度（63 W/mm（2））15%，并且可能在需要高强度光来起作用的泵浦激光器中具有有用的应用。作者描述了高强度太阳光的产生，并报告了其在从直径72.5厘米的望远镜反射镜产生超过3 W激光功率方面的应用，其效率超过了不涉及非成像光学器件的方法通常达到的效率。
The techniques of nonimaging optics have permitted the production of a world-record intensity of sunlight, 72 W/mm(2), by using a sapphire concentrator. Such an intensity exceeds the intensity of light at the surface of the Sun itself (63 W/mm(2)) by 15% and may have useful applications in pumping lasers, which require high intensities of light to function. The author describes the production of high-intensity sunlight and reports its application in generating over 3 W of laser power from a 72.5-cm-diameter telescope mirror at an efficiency exceeding that typically attained in approaches not involving nonimaging optics.
