Time-resolved spectroscopy comes of age It is possible to learn a lot about a sample by exciting it with a pulsed laser and using a very fast detector to measure the resulting emissions and decay as a function of time. Ultrafast lasers and pulse-shaping techniques have helped open up new applications. mark for My Articles 18 similar articles

The Optical Society of America The Optical Society of America (OSA) began in 1916 in Rochester, New York, as a gathering of the field's leading scientists, who agreed to create an organization through which scientific ideas, interests, and discoveries could be shared. The society still adheres to its founders' original goals. mark for My Articles 5 similar articles

Physics tackles processor problem The difference between problems that parallel processing computers are good at solving and those they are not is a bit like the difference between water and ice. Pinpointing the boundary between easy and hard parallel processing problems is a physics puzzle that could lead to better parallel processing software. mark for My Articles 2 similar articles
