Techniques for measuring ultrashort pulses have come a long way in the last 10 years. Marie Freebody speaks to Rick Trebino about the intricacies of working at femtosecond timescales and how the ...

Sources of attosecond-duration light pulses provide the fastest time resolutions available today for observing ultrafast phenomena in atoms, molecules and condensed matter. The measurement of such ...

Full characterization of single ultrashort laser pulses, as needed for attosecond metrology and spectroscopy, requires precise measurement of the offset between the electric field and pulse envelope, ...

Generating ultrashort laser pulses that last a few femtoseconds is a highly active area of research that is finding applications ranging from micromachining to eye surgery. For optimum results it is ...

Ultrashort pulses have been measured in both space and time at and near a focus for the first time. The researchers hope that their technique will help scientists to detect and compensate for ...
