【摘要】 A stable passively mode-locked laser of Nd3+:Gd0.5Y2.5Al5O12（Nd:GYAG） disordered crystal is experimentally investigated both using Z-type and W-type cavities with a semiconductor saturable absorbed mirror.The continuous-wave mode-locked threshold of the absorbed pump power is just 1.8 W.The maximum average output power is 210 mW,which is obtained at the absorbed pump power of 2.3 W.The pulse width is measured to be11.1 ps assuming a Gaussian shape.
