一种向太空提供能量的新方法是在地面上使用高功率连续激光器将能量射到太空中的光伏接收器。这种大型激光器可以位于一个或多个地面位置的无云站点，并使用具有自适应光学校正的大型反射镜，以减少由于衍射或大气湍流引起的光束扩散。这可以导致对电池存储的较低要求，这是由于即使在地球阴影期间阵列的连续照明，以及较高的功率输出，这是由于与太阳能相比，光伏阵列在激光照明下的较高效率以及实现较高照明强度的能力。应用包括在日食期间为卫星提供电力，为由于太阳能电池阵列退化而失败的卫星提供电力，为轨道转移车辆或月球转移航天飞机提供动力，以及为月球上的太阳能电池阵列提供夜间电力。
A new method for providing power to space consists of using high-power cw lasers on the ground to beam power to photovoltaic receivers in space. Such large lasers could be located at cloud-free sites at one or more ground locations, and use large mirrors with adaptive optical correction to reduce the beam spread due to diffraction or atmospheric turbulence. This can result in lower requirements for battery storage, due to continuous illumination of arrays even during periods of shadow by the Earth, and higher power output, due to the higher efficiency of photovoltaic arrays under laser illumination compared to solar and the ability to achieve higher intensities of illumination. Applications include providing power for satellites during eclipse, providing power to resurrect satellites which are failing due to solar array degradation, powering orbital transfer vehicles or lunar transfer shuttles, and providing night power to a solar array on the moon.
