✦ Synopsis

We demonstrated selective amplification of supercontinuum ultrashort optical pulses around 1300-nm and 1550-nm bands by injecting a supercontinuum source into a semiconductor optical amplifier (SOA) and an erbium-doped fiber amplifier (EDFA), respectively. The broadband supercontinuum source was obtained by coupling femtosecond Ti:Sapphire laser pulses into a dual zero-dispersion wavelengths nonlinear photonic crystal fiber. The amplified supercontinuum has fully utilized the gain bandwidth of SOA and EDFA. However, the CW background amplified spontaneous emission increases as a result of the reflection at fiber ends to cause noisy pulse train.

It is shown that application of narrowband pump for non-collinear parametric amplification of supercontinuum radiation is more profitable than of broadband one. The usage of 0.5 nm bandwidth pump with energy of 350 μJ allowed us to get 20 percents signal-to-pump efficiency during amplification of su
