Paper Abstract

Pulse bursting is demonstrated using a pulsed MOPA fiber laser at 1064 nm for percussion drilling of stainless steel. Bursts are configured as fast pulse sequences at tens of MHz, with a temporal envelope in the range from 10 to 420 ns. Their use rapidly enhances the efficiency of material removal by enhancing pulse energy deposition, and quality improvement. Results are shown for various pulse conditions by changing number of pulses, spacing and peak powers. Each pulse burst is collectively triggered and amplified as a single pulse group, at repetition frequencies from singleshot to hundreds of kHz.
