| Abstract: | A diode pumped Nd:YVO4 semiconductor saturable absorber mirrors (SESAM) passive mode-locked intracavity frequency doubled laser was studied. A type
I phase matching LBO frequency doubling crystal was inserted in the cavity. With a pump power of 4.5 W, a 140 mW output of
frequency doubled beam was achieved with LBO, while the power of one fundamental frequency beam was 240 mW with repetition
rate of 85 MHz, and pulse duration of 5.2 ps. |
