There has been progress towards using solar powered lasers for Magnesium production. Having a profitable industrial application to fund and drive and scale the development of solar powered lasers is good news for accelerating solar powered lasers for space applications. They are scaling to 1 megawatt of solar collection and 30 watts of laser per square meter of collection area. A space based system could have 60 watts of lasers since there is no atmosphere blocking sunlight. Space based being application would then need another fresnel lens to focus the lasers for long range beaming.
