Abstract
A doubly Q-switched Nd:GGG laser emitting 1064Â nm wavelength with an acousto-optic modulator (AOM) and a monolayer graphene saturable absorber (SA) is presented to study the pulse characteristics. In comparison with singly passive Q-switched laser (SPQSL) with grapheme SA, the doubly Q-switched laser (DQSL) can effectively shorten the pulse width and improve the pulse peak power. The existence of the ramping behavior of pulse characteristics versus modulation frequency in DQSL is shown. The average output power, the pulse width, the pulse energy and the peak power are related to modulation frequency of AOM, and the point of inflection is dominated by pump power.
