The study introduces a doubly Q-switched and mode-locked laser at 1.3 μm using an acousto-optic modulator and molybdenum selenide saturable absorber, which achieves stable QML pulses with a repetition rate of 1 kHz. It demonstrates a pulse energy of 550 μJ and a Q-switched envelope width of 155 ns at 12 W, showing a 92% reduction in envelope width and a 33-fold increase in pulse energy compared to the singly QML state.
A doubly Q-switched and mode-locked (QML) laser at 1.3 mu m with an acousto-optic modulator and molybdenum selenide saturable absorber is presented. Stable QML pulses with repetition rate of 1 kHz are obtained. The variation in output characteristics with pump power is investigated. A pulse energy of 550 mu J and a Q-switched envelope width of 155 ns are achieved at 12 W. Compared with those in the singly QML state, the Q-switched envelope width is reduced by 92% and the pulse energy increases 33 times in the doubly QML state.
