1 mJ narrow-linewidth pulsed fiber MOPA source at 1535 nm
1 mJ narrow-linewidth pulsed fiber MOPA source at 1535 nm
Narrow-linewidth high power pulsed "eye-safe" erbium-ytterbium doped fiber lasers and amplifiers (EYDFA) are ideal source for LIDAR systems, nonlinear optical conversion, and remote sensing thanks to their compactness, versatility and efficiency. However although recent progress has been made, scaling of the energy and peak power of narrow-linewidth pulses presents many challenges.
Stimulated Brillouin scattering (SBS) is the major impediment for "single-frequency" pulses. Here, in order to avoid this nonlinear effect, we use a fiber with increased core size and reduced length, which allows us to reach a pulse energy of over 1 mJ in 88 ns long pulses. The drawbacks are that the core size increase leads to a transverse multimode output and in addition increases the amplified spontaneous emission (ASE) which limits energy extraction.

Abstract
Narrow-linewidth high power pulsed "eye-safe" erbium-ytterbium doped fiber lasers and amplifiers (EYDFA) are ideal source for LIDAR systems, nonlinear optical conversion, and remote sensing thanks to their compactness, versatility and efficiency. However although recent progress has been made, scaling of the energy and peak power of narrow-linewidth pulses presents many challenges.
Stimulated Brillouin scattering (SBS) is the major impediment for "single-frequency" pulses. Here, in order to avoid this nonlinear effect, we use a fiber with increased core size and reduced length, which allows us to reach a pulse energy of over 1 mJ in 88 ns long pulses. The drawbacks are that the core size increase leads to a transverse multimode output and in addition increases the amplified spontaneous emission (ASE) which limits energy extraction.
