Ultrafast laser with high power and short pulse duration plays a more and more important role in basic scientific researches， precision machining and biomedicine etc. Among the various femtosecond light sources， the laser diode directly pumped Yb-doped all-solid-state bulk femtosecond laser has become one of the research hotspots in the ultrafast laser because of its advantages of compact structure， low cost， reliability and excellent output performance. In particular， the Kerr lens mode-locked Ytterbium-doped all-solid-state femtosecond laser is expected to deliver both an average power of one hundred watts and an pulse duration less than one hundred femtoseconds at the same time. This paper summarizes the research results of Kerr lens mode-locked ytterbium-doped bulky material all-solid-state lasers that generated short pulses with high average power in recent years， and looks forward to it. It also gives a prospect and plan for realizing the mode-locking operations with average power of one hundred watts， pulse energy of ten microjoules and high-power GHz repetition rate， respectively.
