Improvement of Doubly Q-Switching and Mode-Locking Performance with Nd-Doped Mixed Vanadate Crystals

Gang Zhang, Shengzhi Zhao, Bin Zhao, Yonggang Wang

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:Gd0.3Lu0.33Y0.37VO4 incomparison to that achieved with Nd:YVO4, Nd:LuVO4, and Nd:Lu0.2Y0.8VO4. The experiment results show that the Nd:Gd0.3Lu0.33Y0.37VO4 crystal is more favorable than Nd:YVO4, Nd:LuVO4, and Nd:Lu0.2Y0.8VO4 for doubly QML lasers with AO modulator and SWCNT-SA.

Index Terms—SWCNT-SA, doubly QML laser, mixed vanadate crystal.
