Ultrabroadband OPA in YCOB with a sub-ps Pump Source

open access: yesPhotonics, 2023
We demonstrate the broadband optical parametric amplification of near-infrared laser pulses using a single yttrium calcium oxyborate (YCOB) crystal pumped in a noncollinear geometry by a sub-picosecond, milijoule-level source.

Photon bubble turbulence in cold atom gases

open access: yesNature Communications, 2021
Photon bubble turbulence is an astrophysical phenomenon involving radiation transport. Here, the authors report analogous behavior in ultracold gas by observing signatures of photon bubble instabilities in Rb atoms trapped in a MOT.

Predictive modeling of Alfvén eigenmode stability in inductive scenarios in JT-60SA

open access: yesFrontiers in Physics, 2023
The JT-60SA device offers unique conditions before ITER for the study of the interaction of energetic particles with plasma waves. With similar dimensions to JET, e.g., a major radius but with a slightly more elongated plasma volume, JT-60SA is used as a
