Abstract
Development of ultra-intense and ultrafast lasers have promised scientists with unprecedented extreme physical conditions and new experimental techniques. In 2017, the Station of Extreme Light (SEL) project was approved and is under construction at Shanghai now. In this project, a 100 PW laser facility based on all optical parametric chirped pulse amplification (OPCPA) will be developed, which can provide the focused intensity of more than 10 23 W/cm 2. In this letter, the conceptual design of the SEL laser facility is presented. And the latest progress and the status of the frontend R&D, which can be regarded as a small prototype of the SEL facility, is reported. In the future, the SEL-100 PW laser would pave the way for exploring the next frontier of high field physics.
