We use a single walled carbon nanotubes (SWCNTs) absorber to demonstrate a high power mode locking for Nd:YVO4 lasers. Under the pump power of 12 W, continuous wave mode-locked (CWML) pulse were generated with the maximum average output power of 3.6 W and the pulse duration of 7.6 ps. The peak power and the single pulse energy of the mode-locked laser were up to 4.9 kW and 37.5 nJ, respectively. To our knowledge, this is the highest average output power of the CWML laser with the SWCNTs absorber reported.
