gh repetition rate laser at was obtained. The main theoretical and experimental research contents are pleted as follows:(1) This is the first time to realize diodesidepumped passively Qswiched Nd:YAP laser at with V3+:YAG saturable absorber.(2)It’s the first time to calculate optimum curve of initial transmission of the passively Qswitched crystal V3+:YAG, mirror reflectivity efficiency and laser gain, which is helpful for choosing the passively Qswitched crystal. It makes us plete the experiment in timely.(3) According to properties of V3+:YAG on physical and chemical, the relationship of angle between polarization direction of V3+:YAG and the laser polarization direction, excited state absor
