From September 5 to September 8, some of the top experts on Extremely High-Intensity Laser Physics convened at IST for the ExHILP 2017 with more than 110 participants, 58 talks and 42 posters in a conference with lots of exciting progresses, engaging speakers, including a flash presentation of the posters and a lively poster session. The next ExHILP is already scheduled for 2019 in South Korea, and there is already a proposal to host ExHILP 2021, thus guaranteeing an exciting venue for all the developments in these topics. Thank you very much to all the participants: we look forward to welcome you in Lisbon soon!
