Abstract

We have demonstrated a photonic crystal fiber-based regenerative amplifier at 1.078 μm. The input signal pulse energy is 20 pJ in a 12 ns pulse at a 3 kHz repetition rate. At 8.6 W of input pump power, the amplified output pulse energy is 157 μJ, yielding a gain of 69 dB. To our knowledge, this is the highest gain achieved in a fiber-based regenerative amplifier to date at any wavelength.
