The first is to place electrical contacts on the organic laser gain medium and inject charges through them. It is difficult to make a laser in this way, however, because the injected charges absorb ...

Fine tuning: a new theoretical framework for controlling a system’s properties using laser beams has been developed. (Courtesy: iStock/Swillklitch) Laser light could turn a ... confer quite different ...

Researchers at the University of Michigan have just stumbled upon the most important development in laser ... with light particles under just the right conditions. Too much light or electrical ...

A group of scientists led by the US Department of Energy's National Renewable Energy Laboratory (NREL) has designed a monocrystalline mini solar panel that can convert laser light into electricity.

Mitsubishi Electric has now developed an optical receiver that solves this problem by integrating functions to detect both four phase changes of laser light and beam direction. The result is a ...

Scientists can now help blind people "see" by drawing symbols directly into their ... that visual percepts of tiny spots of light produced with electrical stimulation of visual cortex or ...
