This paper developed a low-cost, simple, and good efficient short-pulse fiber laser using the concept of polarization additive-pulse mode-locking (P-APM). Three different types of pulsed lasers were proposed. The pulse widths were about 5 ns, 20 ns, and 400 ns. The average power and repetition rate used to calculate the pulsed energy of 2.34, 3.98, and 86.2 nJ, respectively. The average output power of the pulsed laser increased when connecting with a high-power Erbium/Ytterbium co-doped fiber amplifier (EYDFA) at the fiber laser output. Using the 3A driving current of the pumped laser diode, the gain of EYDFA went up to 28.36 dB with 0 dBm input power. When the amplifier pump laser source operated at 7A, the three kinds of short-pulse lasers were 13.02, 13.27, and 15.67 mW. While the pulse energy were effectively promoted to 367.22 nJ, 606.11 nJ, and 11.46 μJ with 157, 152, and 133 times of amplification, respectively.
