Research progress and prospects of laser diode pumped high-energy laser

High-energy lasers are widely used in materials processing, scientific research, space debris removal, and military counter measures. In recent years, various types of diode-pumped high-energy lasers with high power, high efficiency, and high beam quality have been rapidly developed due to their compact structure, simple system, full electric drive, and unlimited magazines. In this review, we describe in detail the research progress of high-average power bulk solid-state lasers, high-power visible light lasers, high-peak power lasers, high-power fiber lasers, alkali metal vapor lasers and other diode-pumped high-energy lasers at home and abroad. Moreover, we conclude with some perspectives and outlook on their future developments.
