Get this from a library. Overview and future direction for blackbody solar-pumped lasers. [R J De Young; Langley Research Center.]. These methods are (1) imaging concentrators, (2) nonimaging concentrators, and (3) blackbody cavity pumping.
A few important applications for solar pumped lasers were identified but there was not adequate information presented regarding technical and cost considerations so that the suitability of solar pumped lasers could be assessed. A solar-pumped laser (or solar-powered laser) is a laser that shares the same optical properties as conventional lasers such as emitting a beam consisting of coherent electromagnetic radiation which can reach high power, but which uses solar radiation for pumping the lasing type of laser is unique from other types in that it does not require any artificial energy source.
