Abstract

We report on the development of an efficient and simple picosecond diode-pumped solid-state laser source with a versatile repetition rate (typically 1 Hz 1 MHz ) for material processing applications. The laser source is based on a 4 MHz repetiton rate mode-locked oscillator and a passive 3D multipass amplifier both based on Nd : YVO 4 crystals. Micromachining experiments were performed to study the influence of pulse energy on the machining quality for Al, Cu, paper, and glass.
