Abstract
We report an efficient Q-switched Ho3+Pr3+-doped fluoride fiber laser, producing a peak power of 77 W, with pulse width of 78 ns. A slope efficiency of 20% with respect to the launched pump power was achieved. A TeO2 acousto-optic modulator allowed continuous tunability of the pulse repetition frequency from 40 to 300 kHz.
