Engineers use 'shaped' laser pulses in 'ultra-wideband' research

Engineers at Purdue University have developed a technique that could result in more accurate "ultra-wideband" radio signals for ground-penetrating radar, radio communications and imaging systems designed to see through walls.
The researchers first create laser pulses with specific "shapes," which precisely characterize the changing intensity of light from the beginning to end of each pulse. The pulses are then converted into electrical signals for various applications.
