摘要

Since the first report of "A sun-pumped cw one-watt laser" in 1966, optical and laser material advances have continued to improve solar-pumped laser performance. Until now, space-based and terrestrial applications for a "renewable energy" laser were not seriously considered; however, that notion may change with the recent 6.6X improvement in solar-pumped laser-beam brightness figure of merit achieved by researchers at the New University of Lisbon (Lisbon, Portugal). The brightness improvement was demonstrated using a solar-concentration configuration that incorporates a Fresnel lens and both aspheric and parabolic optics.
