Solar Photoresonant Excitation of Semiconductor Lasers and Photoluminescent Devices

摘要

After reviewing briefly the various difficulties encountered in previous efforts to use sunlight for laser pumping, the authors show that one possible way of producing effective pumping is to produce resonant interaction between modulated sunlight and plasma waves in a semiconductor laser. The conditions for the occurrence of such waves by double injection are derived, and the method whereby sunlight modulated in space and in time resonate with the plasma waves to produce regions of unusually high carrier density sufficient to produce the stimulated emission in the semiconductor, is described in detail.
