Abstract
In this letter, a doubly Q-switched 1.06 μm pulse laser with AO modulator and Cr4+:YAG saturable absorber by direct pumping grown-together composite GdVO4/Nd:GdVO4 crystal is demonstrated for the first time. Compared to purely AO Q-switching, the simultaneous use of AO Q-switch and Cr4+:YAG saturable absorber can generate shorter pulses and more symmetric temporal profiles. The thermal lens effect of laser crystal was analyzed.
Research highlights►Doubly Q-switched laser by direct 879 nm pumping GdVO4/Nd:GdVO4 crystal. ►The characteristics of doubly Q-switched pulse laser were investigated. ►The thermal lens effect of different laser crystals was measured.
