We report a new technique for passive Q-switching of low-power lasers, which exploits nonlinear reflection from a liquefying gallium mirror. Self-start Q-switching has been achieved in an Er3+:Yb3+ fiber laser for circulating intracavity powers of only a few milliwatts. The laser produced a continuous train of pulses as short as 1µs at repetition rates of a few tens of kilohertz with peak powers of 0.5W. Due to the broadband reflective nature of the nonlinearity of gallium, the technique should be applicable to a wide range of laser systems.
