The article reports on the effort of researchers in Germany to develop a device that temporally shapes femtosecond laser pulses. This has advantages for applications that include pump-probe spectroscopy, coherent control, and optical processing of information. The technique on retroreflecting grooves intend to contour near-infrared (NIR) pulses based on dividing the pulse into several propagating subpulses through reflecting from an impressive display of miniaturized retroreflector grooves.
