✦ Synopsis

By using both electric-optic (EO) modulator and GaAs
saturable absorber, a doubly actively-passively Q-switched laser
is realized for the first time. Especially, the more symmetric and
shorter pulse is generated in comparison to purely EO-actively or
GaAs-passively Q-switched laser. In addition, a symmetric factor
is defined to describe the temporal symmetry of the pulses. The
experimental results show that it is possible to obtain a more
symmetric pulse in doubly Q-switched laser.
