Light Pulses Get Shorter
A beam of light can be split and recombined into ultrashort pulses with waveforms that have sub-femtosecond features, reports an international team of researchers (Science, DOI: 10.1126/science.1210268). The work opens up a new way to observe and control electron dynamics.
Scientists can also control the structure of the shorter features depending on how the light pulses are combined. That will allow time-dependent study of electron dynamics, says Paul . . .
