Solar Tracking Error in Solar-Pumped Lasers

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


In this chapter are discussed the solar tracking errors and the compensation techniques in solar-pumped lasers. Solar tracking error displaces the focal spot away from its optimal position, shifting the center of the absorption distribution within the laser rod, resulting in less laser output power and poor laser beam quality. The multi-rod approach is here discussed numerically and experimentally, in order to compensate the solar tracking error and enhance stable solar laser emission. A numerical modeling example of solar-pumped laser with tracking error compensation capacity is finally given in this chapter.
