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 $7.6\mathrm{W}$, an average output power of $3.8\mathrm{W}$, pulse energy of $300\mu \mathrm{J}$, pulse repetition rate of $12.5\mathrm{kHz}$, and pulse duration of $30\mathrm{ns}$ was obtained.
