Abstract: High-energy (≥100mJ) ultrafast solid-state lasers with repetition rates and picosecond-scale pulse duration, not only possess terawatt-scale peak power, but also have excellent beam quality, system reliability, and cost-efficiency, making it crucial in fields of advanced manufacturing and detection, laser medicine, and scientific research. In terms of laser gain media, besides titanium sapphire and neodymium-doped garnet, Yb:YAG (Yb:Y3Al5O12) has increasingly been adopted in diode laser-pumped solid-state picosecond laser amplifiers, due to its low quantum defect and broad emission bandwidth. In this work, we have reviewed the reported results of Yb:YAG solid-state lasers with repetition rates, pulse energies of 100 mJ and picosecond pulse duration, operating at both room temperature and low temperature. The crucial output parameters of this kind of lasers such as system efficiency, pulse energy, and beam quality are summarized and their potential applications in high peak power generation, optical parametric amplification, and attosecond pulse generation are also explored.

Key words: solid-state laser amplification, 100-mJ pulse, picosecond laser technology, regenerative amplification, Yb:YAG crystal
