Laser heating of individual cells in culture recently led to seminal studies in cell poration, fusion, migration, or nanosurgery, although measuring the local temperature increase in such experiments remains a challenge. Here, the laser‐induced dynamical control of the heat‐shock response is demonstrated at the single cell level, enabled by the use of light‐absorbing gold nanoparticles as nanosources...
Segmented wave front phase measurement is a key technological topic for next generation of kHz lasers, which will be based on the combination of small-scale laser sources (fibers) before focusing on target, such as in Laser WakeField Acceleration (LWFA) [1].
Adaptive optics loops are now widely implemented on high power laser chains and several industrial solutions exist which are optimized for their specific constrains. However the main goal for adaptive optics loop implementation is to optimize the interaction between laser and matter (gas or solid). In particular, one parameter to optimize for loop convergence is the intensity at the focus of the off-axis...
We validate the use of a quadriwave lateral shearing Wave Front Sensor (WFS) to make an ISO compliant M2 measurement. We compare measurements made following the ISO standard method with those made with the WFS.
