Description
The challenge of producing the next generation of particle accelerators for scientific and societal applications, has been taken up by the High-intensity Community.
One of the main standing issues for creating laser-based accelerators to match or better the performance of traditional accelerators is the requirement that the drive lasers produce simultaneously high peak and high average power with high efficiency>30%. . Even state of the art petawatt lasers typically have average powers of only a few tens of watts with a wall plug efficiency of 10-4. These are pitiful considering that real accelerators will require pulse repetition rates much higher – tens of kHz – and average laser powers of hundreds of kW with wall plug efficiency >30%.
The international Coherent Amplification Network (ICAN) has shown[1] that a novel laser architecture based on a massive array of fibre lasers could be a cost effective solution. In addition to high peak and average powers, excellent efficiency it offers the potential of perfect and digitally controllable beam quality.
