1. A pulse source, comprising:
- a seed source emitting seed pulses, said seed source generating pulses at a repetition rate and comprising a polarization maintaining gain fiber;
at least one polarization maintaining fiber amplifier disposed downstream from said seed source;
one or more pump laser diodes for pumping said seed source and said at least one fiber amplifier;
a bulk optical amplifier receiving amplified pulses from said at least one amplifier and producing output pulses;
an electro-optic or acousto-optic modulator configured as a down counter to reduce a repetition rate of pulses generated by said seed source, said modulator disposed between said seed source and said bulk optical amplifier.

Abstract
The invention describes classes of robust fiber laser systems usable as pulse sources for Nd: or Yb: based regenerative amplifiers intended for industrial settings. The invention modifies adapts and incorporates several recent advances in FCPA systems to use as the input source for this new class of regenerative amplifier.
