Abstract Presented is a novel way to combine snapshot compressive imaging and lateral shearing interferometry in order capture the spatio-spectral phase of an ultrashort laser pulse single shot. A deep unrolling algorithm utilized for reconstruction due its parameter efficiency superior speed relative other methods, potentially allowing online reconstruction. The algorithm’s regularization term represented using neural network with 3D convolutional layers exploit correlations that exist...
Knowledge of spatio-temporal couplings such as pulse-front tilt or curvature is important to determine the focused intensity high-power lasers. Common techniques diagnose these are either qualitative require hundreds measurements. Here we present both a new algorithm for retrieving couplings, well novel experimental implementations. Our method based on expression spatio-spectral phase in terms Zernike-Taylor basis, allowing us directly quantify coefficients common couplings. We take...
Abstract The Centre for Advanced Laser Applications in Garching, Germany, is home to the ATLAS-3000 multi-petawatt laser, dedicated research on laser particle acceleration and its applications. A control system based Tango Controls implemented both four experimental areas. device server approach features high modularity, which, addition hardware control, enables a quick extension of allows automated data acquisition parameters each shot. In this paper we present an overview our...
