A mode-locked laser system achieves average output power of more than 18 watts, in a single transversal mode, with a
pump power of 70 watts. The optical to optical conversion efficiency is about 25%. The output wavelength is 1053 nm
and the mode locked frequency is 150 MHz; the pulse width is less than 80 ps. The peak power reaches kilowatts per
pulse. The wavelength can be converted into 527nm and 351 nm with a nonlinear conversion.
