ABSTRACT
We report on a Kerr-lens mode-locked laser based on an Yb3+-doped disordered calcium lithium niobium gallium garnet (YbCLNGG) crystal. Pumping by a spatially single-mode Yb fiber laser at 976â
nm, the YbCLNGG laser delivers soliton pulses as short as 31 fs at 1056.8â
nm with an average output power of 66â
mW and a pulse repetition rate of â¼77.6â
MHz via soft-aperture Kerr-lens mode-locking. The maximum output power of the Kerr-lens mode-locked laser amounted to 203â
mW for slightly longer pulses of 37 fs at an absorbed pump power of 0.74 W, which corresponds to a peak power of 62.2â
kW and an optical efficiency of 20.3%.
