The attoworld-team welcomes a returnee from the pioneering days:  Prof Alexander Fuerbach from Macquarie University in Sydney. When Ferenc and his team produced the first attosecond flashes of light in 2001 at the University of Vienna, Alexander Fuerbach was a doctoral student in the research group.

He has now returned to complete a sabbatical in Alexander Weigel's group until July. During this time, Alex Weigel and Alex Fuerbach want to work together to increase the output power of the infra-sampler.

"I'm looking forward to working in the attoworld team again," says Alex Fuerbach. “I'll be on long service leave from mid-July, as I've been working at Macquarie University for almost 20 years, so I've accumulated a lot of time.  If I am still needed then, I could well imagine staying with the team even longer.”
