Generation of 2.8 ps pulses by mode-locking a Nd:GdVO4 laser with defocusing cascaded nonlinearity in periodically poled KTP

• A Nd:GdVO4 laser mode locked by self-defocussing cascaded nonlinearity in PPKTP is presented. The cavity had a repetition rate of 200 MHz and the mode-locked output power was 350 mW. Pulses as short as 2.8 ps were obtained with a bandwidth of 0.6 nm.
