In the last few years, ultrafast laser systems have foundunprecedented application success in numerous fields of science and industry, e.g., atto-second science, strong-field physics, bio-photonics, and automotive and aerospace machining fields[1–5]. For now, most of the femtosecond lasers in practical use are configured in chirped pulse amplification (CPA) architectures based on bulk solid-state crystals or flexible gain fibers. The conventional bulk solid-state laser systems have advantages in achieving pulses with high peak power[6–8] and short pulse duration. However, they are also restricted in repetition rate and average power owing to thermo-optical effect induced beam distortion[10–12].
