Paper Abstract

By using cascaded Wavelength Division Multiplexing and pumping in sectionalization method, ASE and feedback were greatly suppressed. At repetition rate of 50kHz and pulse duration of 20ns, gain of amplified signal was 17.1dB with a high signal to noise ratio of 25dB. The whole system is a good choice for a preamplifier of high-power pulse amplification.
