Abstract
The adaptation of laser pulse parameters is required for different material processing steps. Especially if the processing has to be done using a single laser system, a flexible variation of the pulse properties is needed. Especially the generation of pulse bursts with ps spacing enable many refinement process steps. As fiber lasers are suitable in the micro material processing regime due to their excellent beam parameter products and short pulses, an adaptive filter for pulse shaping is highly desired. This work derives a general filter theory for generating pulse bursts from ultrashort pulses and extends it for dispersion compensation. The theory is validated by simulation and experiments with a low repetition rate fiber laser and a commercial programmable optical filter. Simulations prove the viability of pulse burst generation with dispersion compensation. With the experimental setup 2-4 ps pulses with 15-25 ps spacing are generated from one ultrashort pulse.
