Presentations

Frequency Resolved Optical Switching (AM4G.1)
Presenter: adrien leblanc, IPP

We report on a toolbox to generate and characterize the temporal profiles and the CEP of mid-infrared few-cycle laser pulses. Most of the talk will focus on the versatile pulse characterization technique : the FROSt (frequency resolved optical switching).

Authors:adrien leblanc, IPP

Self-Referened Spectral Interferometry With Extended Time Excursion (AM4G.2)
Presenter: Thomas Oksenhendler, iTEOX

Single-shot high dynamic temporal contrast measurement is a key diagnostic for PW class laser. Self-referenced Spectral Interferometry experimentally demonstrates that it will be the solution, up to 100dB over 60ps, for the full pulse bandwidth.

Complete Space-Time Metrology of Ultrashort Laser Pulses With INSIGHT (AM4G.3)
Presenter: François Sylla, SourceLAB SAS

Spatio Temporal Couplings (STC) are ubiquitous in ultrafast optics. Chirped-pulse amplification (CPA) systems rely massively on using well controlled STC. INSIGHT is a new technique commercially available that enables to measure accurately these couplings.

Controls and Diagnostics for BELLA 1Hz Petawatt Laser (AM4G.4)
Presenter: Kei Nakamura, Lawrence Berkeley National Laboratory

The control and diagnostics for the BELLA 1 Hz – 1 PW laser will be presented, with emphases on “user aspect” and “diagnostics to provide inputs to simulations.

Authors:Kei Nakamura, Lawrence Berkeley National Laboratory

At the Core of the Extreme Light Infrastructure: Laser Pulses Metrology (AM4G.5)
Presenter: Daniel Ursescu, ELI-NP

Extreme Light Infrastructure in Europe concentrates several unique-worldwide laser systems. Their outstanding parameters require creative solutions for laser metrology. In this context, solutions implemented at ELI-NP 10PW peak power laser systems will be presented.

Authors:Daniel Ursescu, ELI-NP

In Situ Temporal Measurement of High-Intensity Ultrashort Laser Pulses (AM4G.6)
Presenter: Miguel Miranda, Sphere Ultrafast Photonics SA

We discuss issues that arise when measuring high power ultrashort pulses, compare single shot and scanning approaches, and finally present some recent results of fully on-target pulse characterization using the d-scan technique.
