Ultrafast and ultraintense lasers have ultrafast temporal and ultraintense focal intensity properties. They can create unprecedentedly extreme experimental conditions with ultrahigh time resolution, temperature, and pressure as well as ultrahighstrength field. The ultrafast and ultraintense laser is one of the important tools for frontier fundamental research meant for extending the knowledge of mankind. This paper starts with the analysis of the application and development demands of the ultrafast and ultraintense lasers and then systematically investigates the research status of these lasers in China and abroad. Based on this, the developing routes and targets of ultrafast and ultraintense lasers as well as the related technologies needed for achieving these targets are proposed. Particularly, we proposed the respective key steps for developing ultraintense lasers with ultrahigh peak power and those with high repetition frequency, and emphasized the study of related technologies and ancillary components. Furthermore, several suggestions are proposed for the development of ultrafast and ultraintense lasers in China, including strengthening fundamental researches, improving personnel training, enhancing international cooperation, and promoting market application, hoping to provide references for the steady development of China’s laser technologies.
