We report on the fiber-based amplification of a commercially packaged, fiber-pigtailed-pulsed diode laser operating at wavelength of 1064nm (bandwidth 0.45nm). The cascaded Yb-doped fiber amplifier can operate safely by using cascaded Wavelength division multiplexing (WDM) in each single-mode amplification stage. The total isolation of cascaded WDM can protect the laser diodes from destroyed by feedback of optical power. At repetition rate of 50kHz, pulse duration of 20ns, and average power of 0.5mW, output power up to 1.05W And peak power up to 1.05kW are obtained, with a high signal to noise ratio of 20dB. The whole system is a good choice for a preamplifier of high-power short-pulse amplification. The aim of the experiment is to study the design of preamplifier for high-power short-pulse amplifier via cascaded fiber-based amplifier.
