Gain bandwidth broadening of the continuum-seeded optical parametric amplifier by use of two pump beams

We show that the gain bandwidth of the continuum-seeded single-pass optical parametric amplifier may be easily extended using several pump beams amplifying neighboring regions of the seed signal spectrum. Experimentally we demonstrate more than twofold gain bandwidth broadening of type I phase-match...

Description
Summary:We show that the gain bandwidth of the continuum-seeded single-pass optical parametric amplifier may be easily extended using several pump beams amplifying neighboring regions of the seed signal spectrum. Experimentally we demonstrate more than twofold gain bandwidth broadening of type I phase-matching BBO OPA along with subsequent compression of the amplified signal down to the transform limit.
