Image-based diagnostics of the plasma produced in 1 PW laser experiments

Le résumé fourni par la source

Plasma imaging diagnostics are essential tools for gaining insight into the laser-driven plasma dynamics in experiments with high-power lasers. This study details the design and implementation of an imaging system based on shadowgraphy measurements, integrated with wavefront sensor measurements, during the experiments conducted in the commissioning phase of the Extreme Light Infrastructure – Nuclear Physics (ELI-NP) facility. The shadowgraphy system was employed to capture detailed images of the plasma plume generated by the 1 PW laser pulses directed at both solid and gaseous targets. The wavefront sensor measurements reveal the phase shift of the wavefront of the probe beam as it traverses the plasma channel formed by the laser beam focused into a gas cell. Our findings highlight the importance of these imaging diagnostic techniques in evaluating the complex dynamics of laser-plasma interaction for the advancement of laser-driven particle acceleration.
