High-definition laser pulse shaping for phase only pulse synthesis and replication

Abstract

We report a new femtosecond laser pulse shaping technique based on high-definition acousto-optic diffraction. Phase-only generation of pulse replicas free of satellite pulses is demonstrated experimentally using multiple independent comb shaping with randomized widths of the comb segments. The acousto-optic delay line operates at 10 kHz repetition rate with the maximum delay of 10 ps.
