Abstract
A micro processing used LD end-pumped Nd:YVO4 all solid-state picosecond pulse laser was demonstrated under the semiconductor saturable absorption mirror(SESAM) mode-locking technology and regeneration amplifier technology, by using BBO crystal as electro-optic crystal and diode-side-pumped Nd:YAG. 1064nm laser was obtained with 1.47mJ single pulse energy, 15ps pulse width at 1 kHz repetition rate and the pulse energy fluctuation was less than 0.6% in 3 hours operation. Finally, through the galvanometric we got the beam focused, realizing the steel plate processing which thickness was 0.5mm and the aperture radius was 25.5μm.
