The Laser Institute of America (LIA) is revising Z136.8 Standard for Safe Use of Lasers in Research, Development or Testing. This standard provides recommendations for the safe use of lasers and laser systems that operate at wavelengths between 180 nm and 1 mm and are used to conduct research or used in a research, development, or testing environment. This environment is not limited to universities and national laboratories, but includes medical research facilities and high-tech product development evaluation settings.

Multiple Input Multiple Output
Noncooperative Cellular Wireless with Unlimited Numbers of Base Station Antennas
New York University Department of Electrical and Computer Engineering
ABSTRACT: A cellular base station serves a multiplicity of single-antenna terminals over the same time-frequency interval. Time-division duplex operation combined with reverse-link pilots enables the base station to estimate the reciprocal forward- and reverse-link channels. The conjugate-transpose of the channel estimates are used as a linear precoder and combiner respectively on the forward and reverse links. Propagation, unknown to both terminals and base station, comprises fast fading, log-normal shadow fading, and geometric attenuation. In the limit of an infinite number of antennas a complete multi-cellular analysis, which accounts for inter-cellular interference and the overhead and errors associated with channel-state information, yields a number of mathematically exact conclusions and points to a desirable direction towards which cellular wireless could evolve. In particular the effects of uncorrelated noise and fast fading vanish, throughput and the number of terminals are independent of the size of the cells, spectral efficiency is independent of bandwidth, and the required transmitted energy per bit vanishes. The only remaining impairment is inter-cellular interference caused by re-use of the pilot sequences in other cells (pilot contamination) which does not vanish with unlimited number of antennas.
