主　　题：YAG MHz carbon nanotube mode-locked femtosecond Cr:YAG laser Cr 

摘      要：We demonstrate a femtosecond Cr：YAG laser mode-locked by a carbon nanotube saturable absorber mirror（CNT-SAM） at a repetition rate of 550 MHz. By employing the CNT-SAM, which exhibits a modulation depth of 0.51% and a saturation fluence of 28 μJ∕cm^2 at 1.5 μm, we achieved a compact bulk Cr：YAG laser with selfstarting mode-locked operation near 1.5 μm, delivering an average output power of up to 147 m W and a pulse duration of 110 fs. To our knowledge, this system provides the highest repetition rate among reported CNT-SAM mode-locked Cr：YAG lasers and the shortest pulse duration among saturable absorber mode-locked Cr：YAG lasers with repetition rates above 500 MHz.
