Paper Abstract

We demonstrate a pulsed green fiber laser using highly efficient frequency conversion in a robust single-pass configuration of a narrow Linewidth source based on specialty LMA fibers for enabling high pulse energies and peak power. The ability to reach short pulses that are selectable from 1 to 20ns, peak powers up to 20kW, and pulse energies up to 200 μJ in the 532nm wavelength regime, while maintaining excellent beam quality with high repetition rate capabilities, enables new opportunities for next-generation material processing applications. We have demonstrated a variety of processes with high throughput and quality, including glass cutting, wafer cutting, PCB cutting, and ceramic scribing.
