The second fusion of laser and aerospace - an inspiration for high energy lasers

Since the first laser was invented, pursuit of high-energy lasers (HELs) has always been enthusiastic. The revolution HELs pushed by fusion and aerospace in 1960s, with chemical rocket engines giving fresh impetus to birth gas flow lasers, which finally turned megawatt from dream into reality. Nowadays, development entered age electricity as well engines. properties current electric are highly consistent HELs’ goals, including electrical driving, effective heat dissipation, little medium consumption extremely light weight size, inspired a second motivated exploration for potential HELs. As an exploratory attempt, new configuration diode pumped metastable rare demonstrated, gain generator resembling rocket-engine improved power scaling ability.
