A new publication from Opto-Electronic Advances, DOI 10.29026/oea.2023.220046 discusses table-top optical parametric chirped pulse amplifiers. The invention of Chirped Pulse Amplification (CPA) ...

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 ...

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 ...

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 ...

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 ...

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, ...

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 ...

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 ...

A research collaboration coordinated by Lawrence Livermore National Laboratory (LLNL) has developed new large-scale diffraction gratings that are thought to be capable of delivering ultrashort laser ...
