Abstract

We report an oblique incidence on semiconductor saturable absorber mirror (SESAM) method in the LD pumped passively mode-locked Nd:YVO₄ picosecond laser in this article, making SESAM as the intracavity reflecting mirror, which produces maximum average output power of 1 W, pulse repetition rate of 120 MHz, and stable continuous mode-locked pulse at 1064 nm with the pulse width of 19.2 ps. To our knowledge, this was the first demonstration that got CW mode-locking in standing-wave laser with a reflected mirror SESAM in oblique incidence way.
