摘要: We report on a Kerr-lens mode-locked (KLM) femtosecond Yb:CaYAlO$_{4}$ (Yb:CYA) laser operating at a repetition rate of 1.04 GHz, pumped by a single-mode fiber laser. The laser delivers an average output power of 1.37 W with a pulse duration of 109 fs. Potential improvements, including scaling the pump power, increasing the repetition rate, and further reducing the pulse duration, are discussed. This study contributes to the advancement of Watt-level GHz femtosecond laser generation and its applications.
