Abstract

The objective of the Apollon 10 PW project is the generation of 10 PW peak power pulses of 15 fs at 1 shot min??1. In this paper a brief update on the current status of the Apollon project is presented, followed by a more detailed presentation of our experimental and theoretical investigations of the temporal characteristics of the laser. More specifically the design considerations as well as the technological and physical limitations to achieve the intended pulse duration and contrast are discussed.

1 Introduction: Apollon design and status

The Apollon laser, currently under construction at Orme des Merisiers, Saclay, France, will be among the first multi-PW installations in the world devoted to the study of high-intensity laser matter interaction in unprecedented regimes and with peak intensities surpassing $2\times 10^{22}~\text{W}~\text{cm}^{-2}$. The final goal of the Apollon laser is the generation of 10 PW pulses corresponding to energy of 150 J and pulse duration of 15 fs at a repetition rate of $1~\text{shot}~\text{min}^{-1}$.
