Attosecond ambition

Femtosecond lasers are a vital precursor to generating even shorter attosecond pulses. Andy Extance investigates what's involved, and whether these most fleeting flashes could be exploited commercially


Power of the pulse

Although no commercial systems are yet available, attosecond lasers are the subject of intense research. DARPA, for instance, launched a $6.9 million project on applications of attosecond pulse generation in August of this year. Katia Moskvitch looks at the technology required to generate these ultrashort laser pulses


As fast as it gets

As ultrafast laser research progresses onwards from femtosecond pulses, Stephen Mounsey looks at the cutting edge of attosecond lasers, and asks how to ready experimental lasers for the factory floor
