The second fusion of laser and aerospace—an inspiration for high energy lasers
Opto-Electronic Advances, 2023 Since the first laser was invented, the pursuit of high-energy lasers (HELs) has always been enthusiastic. The first revolution of HELs was pushed by the fusion of laser and aerospace in the 1960s, with the chemical rocket engines giving fresh impetus to
