Wide-area infrared beams can be used to establish high-speed digital links between portable terminals and a base station, allowing construction of in-building wireless local-area networks. We discuss key impairments to high-speed communication using non-directional infrared links: small received signal power in the face of potentially intense ambient(More)
We review recent experimental and theoretical work on the use of counterpropagating light to enhance high-order harmonic generation through all-optical quasi-phase matching. Also presented is a new technique for measuring the coherence of high harmonics in the nonlinear medium. This information is crucial for understanding the process of harmonic generation(More)
