Coherently tiled titanium:sapphire laser amplification provides a relatively easy and inexpensive way to surpass the current 10-petawatt limit. “By adding a 2×2 coherently tiled titanium:sapphire high ...

Ultra-intense ultrashort lasers have a wide-ranging scope of applications, encompassing basic physics, national security, industrial service, and health care. In basic physics, such lasers have become ...

Ultrafast laser pulses, typically defined by durations in the femtosecond to picosecond range, have revolutionised both fundamental science and applied technology. Their generation and amplification ...

Since the earliest demonstration of chirped-pulse amplification (CPA) and optical parametric chirped-pulse amplification (OPCPA), femtosecond lasers have been able to deliver ultrahigh peak powers up ...

Mentor: Burcin Bayram, Ph.D. A chirped pulse is a short optical or electromagnetic pulse in which the frequency and phase change over time. The use of chirped laser pulses, where the laser frequency ...

Ultrafast lasers rely on the precise control of pulse characteristics to achieve durations in the femtosecond regime. At the heart of this control lies the engineering of dispersive mirrors, which are ...

In the same way that a camera flash can ‘freeze’ rapidly moving objects, making them appear as if they are standing still in photos, extremely short laser pulses can help light up ultrafast processes, ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...
