Paper Abstract

We are presenting an inversion estimator based controller for master oscillator power amplifier (MOPA) laser systems. The controller is here applied to a Ytterbium doped MOPA fiber laser. The control algorithm regulates the pump power to limit the amplifier gain, so operation is restricted to the boundaries set by damage threshold or nonlinearities. In particular, it allows low pulse repetition frequency operation down to single shot and arbitrary gating.
