Due to their unique advantages, such as high efficiency, reliability, flexibility, and robust configuration, solid-state lasers have experienced rapid development in recent years, resulting in tremendous new applications being induced. To provide a comprehensive view of the latest advances in the field, the Research Topic Advanced high-power solid-state laser technology was launched in 2023, which accepted eight high-quality articles [1].

Since the first demonstration of lasers, continuous progress in the development of laser technology, especially solid-state laser technology, has led to numerous new applications and capabilities. Solid-state lasers, including fiber lasers, crystal lasers, and ceramic lasers, have the unique advantage of high efficiency, reliability, flexibility and robust configuration.
