Gain-managed nonlinear amplification of ultra-low repetition rate mode-locked pulse

Abstract

In this investigation, we conducted a study on the amplification of ultra-low repetition rate pulses, specifically in the 0.5 to 16 MHz range, utilizing gain-managed nonlinear techniques. The research was centered around the implementation of a 1064 nm all-polarization-maintaining fiber mode-locked laser, which was seeded with an acoustic-optical pulse picker to regulate the pulse repetition rate. This experimental approach significantly enhanced the nonlinear pulse propagation effects across various pulse repetition rates at 1064 nm, offering new insights into the dynamics of GMN amplification in ultra-low repetition rate regimes.
