Abstract—A powerful and stable LD end pumped Nd:YVO4 passively mode-locking oscillator by SESAM
was demonstrated. At the pumping power of 30 W, 7 W output was obtained with repetition rate of 79.5 MHz
and pulse duration of 15 ps. The beam quality factors M2 were measured to be 1.30 and 1.33, respectively.
