Abstract
By using both the single-walled carbon nanotube saturable absorber (SWCNT-SA) and an acousto-optic (AO) modulator, the stably doubly Q-switched and mode-locked (QML) lasers with Nd-doped mixed vanadate crystals have been realized. The doubly QML laser characteristics are measured. The doubly Q-switching and mode-locking performances are found to be greatly improved by use of Nd:Gd<sub>0.3</sub>Lu<sub>0.33</sub>Y<sub>0.37</sub>VO<sub>4</sub> incomparison to that achieved with Nd:YVO<sub>4</sub>, Nd:LuVO<sub>4</sub>, and Nd:Lu<sub>0.2</sub>Y<sub>0.8</sub>VO<sub>4</sub>. The experiment results show that the Nd:Gd<sub>0.3</sub>Lu<sub>0.33</sub>Y<sub>0.37</sub>VO<sub>4</sub> crystal is more favorable than Nd:YVO<sub>4</sub>, Nd:LuVO<sub>4</sub>, and Nd:Lu<sub>0.2</sub>Y<sub>0.8</sub>VO<sub>4</sub> for doubly QML lasers with AO modulator and SWCNT-SA.
