Abstract

We demonstrate an efficient, high-pulse-energy, passively Q-switched Yb-doped fiber laser with AlGaInAs quantum wells (QWs) as a saturable absorber. The AlGaInAs QW material is designed to provide a large modulation change and a quite-low nonsaturable loss. At an incident pump power of 7.6 W , an average output power of 3.8 W , pulse energy of 300 μ J , pulse repetition rate of 12.5 kHz , and pulse duration of 30 ns was obtained.
