A research team in Ehime University found a drastically amplified ring-opening reaction yield in aqueous nanoparticle colloids of a photochromic diarylethene when induced by an intense nanosecond ...

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 ...

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 ...

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 ...

Laser pulse amplification in plasma systems exploits the high damage threshold and nonlinear optical properties of ionised gases to overcome limitations of solid-state optics. By using a long, intense ...

In this study, we numerically simulate the evolution of the orbital angular momentum (OAM) spectrum of a vortex laser beam in the optical parametric chirped pulse amplification (OPCPA) process, which ...
